| Outline of Final Research Achievements |
We carried out fundamental research aimed at facilitating the effective use of geochemically abundant elements that make up a large average percentage (clarkes) of the Earth's crust, e.g., silicon (25.8 clarke). We have succeeded to deposit silicon atoms on copper and silver single crystal surfaces, produced two-dimensional silicon structures, and elucidated the elementary processes in reactions with methyl chloride and other compounds. We thus aimed at being able to tune the Rochow reaction, an important process in the industrial synthesis of silicone. We were able to elucidate and determine the reactivity of copper, copper alloy, and silver surfaces used as actual substrates to grow silicon layers. Furthermore, we succeeded to produce two-dimensional structures and determined how the reactivity changes with the choice of substrate used to grow silicon layers.
