Working Principle New ESCA Facility :
Electron spectroscopy for chemical analysis (ESCA) instrument comprises of X-ray photoelectron spectroscopy (XPS), Ultra-violet photoelectron spectroscopy (UPS) and Auger electron spectroscopy (AES) / Scanning Auger Microscopy (SAM).
The surface to be analyzed is placed in a vacuum environment and then irradiated with photons (X-ray or Ultra-violet). The incident photons release electrons (called photoelectrons) from their electronic structure (core-levels and valence band) and ionize the atoms. The kinetic energy and the number of photoelectrons are precisely measured and counted respectively using an analyzer-detector based on which the binding energy and the intensity of the photoelectron are determined. AES/SAM is based on the Auger effect (series of internal relaxation events upon ionization of core level) leading to emission of electrons called Auger electrons. It uses primary electron beam (3 to 10 keV) and the possibility to focus and scan this primary electron beam in nm and Î¼m range. The Auger electrons are part of the secondary electron spectrum with characteristic energy allowing one to identify the emitting element. The experimental setup is somewhat similar to that of SEM with a difference, that is, the electrons are not only used for imaging but also for chemical identification of the surface atoms.
Limitations: ESCA can detect all the elements except H and He. The detection limit is 0.1%

Frequently Asked Questions
o What is the registration procedure for using this facility and how many samples one can do?
Ans: You can register your request at the link Submit new request. You can submit three samples in one slot. However, in case of XPS-depth profiling you can submit one or two sample (total acquisition time limited to 6 h), as depth-profiling is a lengthy experiment. The samples of the duly registered person only will be accepted. Further registration should be avoided until the slot for existing registration is completed.
o Whether XPS and UPS analysis is possible on same samples in one submission?
Ans: XPS analysis followed by UPS analysis on same samples is possible. Please make two separate requests, one for each mode.
o How long will it take to get a slot, and do I need to be present during the experiment/data collection?
Ans: Normally it takes about two weeks to get a slot, but it could vary depending on the load. The given slot is for submitting the samples. Typically the samples are loaded in the system on the day of your slot and are run unattended (the instrument is automated) in the night or on the subsequent day. You are encouraged to be present during analysis of your samples. You can inform the lab staff so that the analysis is scheduled during working hours.
o What is the typical experimental routine for XPS analysis?
Ans: For a typical XPS investigation a broad survey (wide) spectrum is obtained to identify elements present on the sample surface. The survey spectrum is recorded with analyzer pass energy of 160 eV or 80 eV and large area aperture. These settings provide higher sensitivity and adequate resolution for elemental identification. Once the elemental composition is obtained narrower detailed scans of selected peaks can be recorded at lower pass energy (~ 20 eV) to get better resolution for a more comprehensive picture of the chemical state and composition.
o What is the depth of analysis (surface sensitivity) in XPS and AES? Is it possible to vary the analysis depth?
Ans: The depth of analysis in the case of both XPS and AES is same and is in the range 5 to 10 nm. The analysis can be made more surface sensitive by tilting the sample (changing the emission angle).
o Whether it is possible to record SEM and do XPS analysis?
Ans: It is not possible to do SEM and XPS analysis together. SEM is with Auger analysis and is used for point analysis (< 100 nm) and to generate chemical maps.
o My sample is non-conducting. Is it possible to do XPS and obtain chemical state information?
Ans: It is possible to do XPS on non-conducting samples as the ESCA instrument is equipped with charge neutralizer. However, for chemical state information accurate charge correction to binding energy scale using a reference peak is required. Usually adventitious carbon peak appearing at 284.8 eV can be used for this purpose.
Sample Preparation and Analysis
o Whether liquid samples can be analyzed?
Ans: It is not possible to analyse liquid samples. However, liquid samples may be drop casted on solid substrates like silicon, aluminium foil, gold film etc. and should be dried completely. Wet and greasy samples are not accepted. Caution: ESCA is an ultra high vacuum (UHV) system and any out-gassing from sample will contaminate the system!!!
o Whether it is possible to do sample drop casting and drying in ESCA lab?
Ans: It is not possible in ESCA lab and users have to bring their samples in ready-to-load form. However, if required doctor blade and diamond cutter are available to cut the sample to required size. The samples should be completely dry, free from any solvent and should be stable in UHV conditions.
o Is it possible to analyze powder samples in ESCA system?
Ans: ESCA is a UHV system and hence light weight fine powder samples are likely to fly-off and contaminate the pumping system unless stick properly to sample holder. Therefore, powder samples should be made in to pellet or in to thin coating on substrates like silicon, aluminium foil, copper etc. with good adhesion on its own. No additive should be used as it will interfere with the analysis. Pressing powders in to indium foil is another method.
o Is it possible to do surface cleaning of powder samples using sputter ion gun in ESCA system?
Ans: Powder samples are not possible to sputter as the powder particles are likely to move during ion bombardment. Also, there is a possibility of shadow effect and inhomogeneous sputtering.
o If carbon is element of interest, what is the reference for charge correction?
Ans: In this case you need to identify some element of your sample itself for which you should be sure of its binding energy. Alternately, you can intentionally add some element that will remain unchanged during processing of your sample and whose chemical state / binding energy is well known. Evaporating a small gold dot will also serve the purpose.
o After surface cleaning adsorbed carbon disappears. In that case what is the reference?
Ans: In this case, it is likely that there may be a trace amount of Ar from ion sputtering process present on the sample surface. The Ar 2p core level peak at 242.3 eV can be used for charge correction. In the absence of this the solution same as discussed above may be used.
o What happens to samples after analysis?
Ans: If the samples are to be recovered and returned, you should clearly indicate the same at the time of submitting the samples for analysis. After two to three days of receiving the data (completion of the analysis) the samples can be collected from the lab between 9:30 AM to 11:00 AM. Uncollected samples will be disposed off after ten days of intimation of the completion of the work and no reminders will be sent.
o Does the ESCA lab provide elemental quantification and peak fitting analysis?
Ans: ESCA lab provides the elemental quantification based on survey (wide) spectrum. However, users are advised to verify / cross-check themselves, as sometimes there are overlapping peaks and the operator may not have full details of your sample while quantifying. Peak fitting analysis of high-resolution scans should be performed by users taking in to account the literature and data-base.
o Which software I can use for peak fitting analysis of XPS spectra?
Ans: XPS peak fitting analysis is to be performed using specialized software meant for XPS and AES analysis. Licensed commercial softwares “ESCApe” and “CASA XPS” are available for institute users. Users can download the ESCApe software from the link provided in email received along with data, while the demo version of CASA XPS can be downloaded from internet and later obtain the license from ESCA lab. The .experiment file can be directly opened in ESCApe software, while in the case of CASA XPS software you need it in .vms format (this format conversion can be done in ESCApe software).
o Whether the facility is to be acknowledged in publications?
Ans: If the data obtained from ESCA facility is used in the publications/reports/thesis, the facility must be acknowledged as “Central surface analytical facility (ESCA Lab) of IIT Bombay” with due feedback through email to esca [at] iitb [dot] ac [dot] in.
