assisted by scanning tunneling microscope

Abstract
We report experiments of VUV laser photodesorption of
hydrogen from Si(100)
:H surfaces assisted by an UHV room temperature
scanning tunneling microscope (STM). The variation of isolated dangling
bonds created has been measured for several fluences by a statistical
analysis of the STM observation as a function of the irradiation dose.
Structural surface modifications are discussed as well as the signature of
photochemical processes.
