Silicon Materials
After hydrogenation, the bandgap width of α-Si:H is about 1.7 eV. Amorphous silicon is usually formed as thin film. In contrary to crystalline Si, α-Si has higher lattice potential energy and is in thermodynamic metastable state. After heat treatment, α-Si thin film can be transformed to nano-Si, micro-Si, or even poly-Si thin films.
