【请教】求助紫外光谱计算半导体能带?(100?Forgot to mention that, as shown in the correlation: ^(1/n) vs. (hv-Eg), we don't need to measure the absorption coefficient anymore to obtain the bandgap energy. I have seen so many diffrent methods for bandgap determination. But in my opinion, this so far is the most appropriate one. Also, 1240/wavelength is just a correlation used to determine the photon energy for a single wavlength light, cannot be used for calculating the bandgap energy of a semiconductor material.查看更多
