非晶硅量子点（QD）中的氢化对相应的光学性质和能带结构具有显著影响，从而产生具有独特特性的量子限制复合材料。a-Si：H量子点的合成是用大气压等离子体工艺来证明的，该工艺允许精确控制高度化学反应性的非平衡环境，温度远低于Si量子点的结晶温度。
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.
