采用金催化化学腐蚀和钝化两个过程成功制备了黑硅。利用原子力显微镜、分光光度计、红外光谱仪和光致发光光谱仪分别对黑硅的微观结构、反射率、表面状态和发光性能进行了研究。结果表明:黑硅表面呈现山峰状的微观结构,其平均反射率可低至3.31%。光致发光光谱上出现了3个发光峰,分别由量子限制效应、硅氧烯、杂质和缺陷引起。
The black silicon has been successfully produced by Au particle-assisted chemical etching. The microstructure, reflectance, surface morphology and photoluminescence properties of black silicon have been investigated by atomic force microscope, spectrophotometer, infrared spectrometer and photoluminescence spectrometer, respectively. The results show that the obtained black silicon exhibits a mountain-like structure with the average reflectance of 3.31%. The mechanism of black silicon produced by Au particle-assisted chemical etching is the combination of etching effect and passivation effect. The photoluminescence spectrum can be separated into three peaks which results from quantum confinement effect, siloxene, impurity and defect, respectively.
