Professor Yukichi SHIGETA
In our laboratory, we are going to study the (111) surface of Si, which is in general use as a semiconductor material with STM and RHEED. We intend to investigate, (1) Phase transition of the Si(111) surface from 7x7 into a 1x1 structure and surface melting at high temperature, (2) Surface electronic structure change by Boron doping, (3) Structure change and surface roughening during homo-epitaxial growth of Si，and (4) Self-ordering of Ge quantum dots on the Si(111) surface.
