| Fourier transform photoemission spectroscopy (1996) | |||||||||||||
Abstract | |||||||||||||
| It is shown that photoemission spectra can be obtained by exciting the electrons with two phase-correlated wave trains. The phase-correlated wave trains are obtained by sending broad-band ultra-violet light, coming from a deuterium lamp, through a Michelson interferometer. It is possible to stabilize the interferometer within 20 nm on a time scale of a few minutes and is realized without active stabilization. The Fourier transform of the time-dependent electron yield from a polycrystalline silver sample is almost identical to the spectrum determined with the monochromator. | |||||||||||||
