1.	AES is more sensitive than XPS because of which of the following factors?(a) Binding energies of electrons(b) Kinetic energies of electrons(c) Mass of electrons(d) Mass to charge ratio of electronsI have been asked this question during a job interview.I'm obligated to ask this question of Auger Electron Spectroscopy topic in portion Electron and Ion Spectrometers of Analytical Instrumentation
Answer» The correct option is (b) Kinetic energies of electrons For explanation: AES is more SENSITIVE than XPS because of the difference in kinetic energies of electrons. ION etching is SOMETIMES NECESSARY for AES.
