Surface Electronic States and Field-Ion Image Intensity of Metals

Abstract

The variation of the regional image intensity with the applied voltage was measured for the (001), (011) and (111) planes of W and Mo tips in the field-ion microscope. As the result, it was found that the regional image intensity of (111) plane of W and that of (001) plane of Mo tips didn't increase monotonically with the applied electric field. Total image intensities for W, Mo, Ir and Re were also measured and it was found that they decrease in the order of Re, Ir, Mo and W.
