摘要
We have used scanning tunneling microscopy and spectroscopy (STM/S) to study multiple pn junctions on cross-sectional surfaces of both Si and GaAs devices. The spectroscopy results indicate that pn junctions can be resolved at the nanometer scale by using the two-dimensional STS technique. STM is also used to identify Zn dopants on GaAs(110) surfaces, A detail dopant location identification method is presented. (C) 1998 American Vacuum Society.
