Research Abstract

This research subject was planned to get the insight for chemical bonds between Si substrate surface atoms and deposited metal atoms to understand and classify structures of surface metal silicides. Many surface silicides have been found by experiments, but the number of determined structures is small for lack of guiding principle of chemical bonds between Si and metal atoms. We have conducted the following subjects and obtainedresults.
(1)Determination of the Si(111)-(4x1)-In structure by LEED I-V analysis : we have determined this structure and discussed a structural change from(4x1) to (8x1)p1g1 at low temperature.
(2)Observation of initial processes of the Si(111)-(3x2)-Ba structure by STM : we have observed intermediate local structures such as propeller-like SiBa clusters and Si magic clusters.
(3)Structural phase transition in the Si(111)-(√3x√3)-Ag structure studied by surface X-ray diffraction : the phase transition below 150 K has been assigned not to order-disorder transition.
(4)Molecular orbital theory calculations on Na,Mg an Al atoms on the ideal Si(111) surface.
