Summary on Grant Application Form
Semiconductor surfaces play a significant role in many technological applications. However, clean semiconductor srfaces are highly reactive due to the presence of dangling bonds. Clean surfaces may be 'passivated' by a variety of techniques. Essentially, in order to understand the passivation phenomena, it is important to examine the role played by adsorption of suitable chemical species. Professor Y Fukuda is a leading experimentalist, with research activities focussed on (i) study of structure and electronic states of compound semiconductors and their passivation, (ii) fabrication and characterisation of atomic wires on compund semiconductor surfaces, and (iii) fabrication of compound thin films and nonostructues using metalorganic compunds. I met him twice, in 2001 and 2003, when we both presented invited talks on semiconductor passivation at the second and third International Meeting on Semiconductor Surface passivation in Ustron, Poland. On both ocassions we felt that his experimental studies using STM and my theoretical investigations using the pseudopotential-density-functional theory are trying to address similar issues regarding surface passivation. However, at both ocassions time was too short to get together to discuss any collaborative effort in this direction. This proposal is to seek a small grant for me to visit his laboratory and explore the possibility of collaboration on developing our understanding of passivation of compound semiconductor surfaces such as III-V(111)A and III-V(111)B by deposition of elements such as sulpher. In addition, possibility of collaborative research on atomic wire formation on semiconductor surfaces will also be explored. Results of our current research on nonowires will be presented and discussed at the ICFS-12 conference organised by Professor Fukuda at Hamamatsu.
