For Multipak, anyone know when we need to use the "Shft" feature to shift the spectrum? Like the example in 35:54 is shifted, indicated by (Shft) in red colour beside the sample description, but those in 20:07 etc aren't

Thanks for providing more threads to work XPS data analysis. Can anyone explain what is the 'Si' peak obtained at 99.66 eV in the video at 35.21in spin-orbit coupling examples?

34:07 I think you should not ignore spin orbit splitting of the oxide. In the shown example you can see that the fit is not good. Its just an unnecessary simplification.

At 7:13, is there a kinetic energy term missing in the "Ionization Energy =..." equation?

Can we do XPS of glass coverslip? Dimension is less than 10mm.. Is there any special care to be taken of?

Hello . Why xps not detect H and He ?

H and He only have valence and not core electrons.

In my experiment, even if no bias is used, the cutoff edge can also be measured. so why you not directly measure the spectra above 17eV in UPS to directly obtain the Ef?

Ty for sharing the video. On slide 35, what causes the initial, t0, spikes on the Na and Li curves?

Very interesting presentation and comprehensive explanation! But on some graphs there are no values on the y axis. It will be interesting what counts did you get on these samples...

is it possible mitigate charging issue to pump electrons from valence band to conducting band using UV light (~5eV, photon energy slightly higher than bandgap)?

Beautiful examples of the versatility of this technology. What is the life of the Cr target compared to the Al target? does the chromium target allow you to use higher beam energy without compromising target life versus Al to help compensate for the lower electron cross-sections for the higher energy photons?
