Thin Film and Crystal growth on Semiconductor Surfaces — •Soon Jung Jung — CRANN, TCD, Dublin 2, Ireland
The challenges to use the unique properties of surface onto the fascinating technologies are quite exiting. As a chemist, the research interest is to develop new ways to modify the surface properties by attaching organic molecules on the semiconductor surfaces and to understand their interfacial architecture at the atomic level. Various adsorption structure and mechanism of simple gas phase molecules: H2, liquid phase molecules: pyrimidine (C4H4N2), water (H2O), thiophene (C4H4S) and the complex solid phase molecules: purine (C5H4N4), histidine (C6H9N3O2) will be introduced. In the second part, by using the unique surface properties, I will introduce a novel method to synthesize single crystal NWs by using the surface energy difference between several materials. By simply heating a multilayer film, the energy stored up in the film is released by heating to promote NW formation. This low temperature homogenous growth process does not require added growth precursors and produces high quality single crystalline materials. This method is general so that I could demonstrate Au NW, Cu NW, Fe Nano block and carbon nano tube growth. I will introduce these results and discuss about the future application of this method.
