Study on the atomic configuration for low-energy electron diffraction analysis on ZrO/W(100)

Abstract

The low energy electron diffraction (LEED) pattern of ZrO/W(100) low work function surface was analyzed using the intensity versus voltage (I-V) method. The LEED pattern was taken using a charged coupled device camera and the intensity signals were analyzed using a personal computer. The analysis suggests that the horizontal dipole atomic arrangement must be considered for obtaining a reliable I-V curve.
