Outline of Final Research Achievements |
The purpose of this work is to realize new silicon (Si) nanocrystal-based functional materials by impurity doping in combination with the quantum size effects. In nanocrystals, confined excitons can interact with impurities on the surface. Therefore, chemical elements with very small solid solubility in bulk Si crystal can be doped to Si nanocrystals. We will develop Si nanocrystals in which different kinds of impurity atoms, e.g., n- and p-type shallow impurities, rare earth ions, bismuth ions, etc., are doped and reveal the linear and nonlinear optical properties.
