Field emission of clean and oxidized Mo<110> microtips

In this paper, measurements of field emission taken on a molybdenum<110> microtip under ultrahigh vacuum conditions and as a function of oxygen exposure were reported. Auger electron spectroscopy (AES) was used to examine the clean and oxygen saturated surface of the Mo surface and the peak-to-peak ratio of O (KLL) to Mo (LMM) as a function of oxygen exposure.
