Abstract

Hydrogenation in amorphous silicon quantum dots (QDs) has a dramatic impact on the corresponding optical properties and band energy structure, leading to a quantum-confined composite material with unique characteristics. The synthesis of a-Si:H QDs is demonstrated with an atmospheric-pressure plasma process, which allows for accurate control of a highly chemically reactive non-equilibrium environment with temperatures well below the crystallization temperature of Si QDs.

摘要

非晶硅量子点（QDs）中的氢化对相应的光学性质和能带能量结构有显著影响，从而形成具有独特特性的量子限制复合材料。采用大气压等离子体工艺展示了非晶硅氢量子点的合成，该工艺能够精确控制高度化学反应性的非平衡环境，且温度远低于硅量子点的结晶温度。
