薄膜禁带宽度计算
|
|
|
1. 由透过率得到吸收系数：α=（-1/d）*ln(T) （d是样品厚度，单位取cm，T是透过率（无量纲），就是透射谱的纵坐标数值，最大是100%） 2. 将波长换为能量 hv(eV)=1240/wavelength(nm) 3. 确定半导体带隙类型，如果是直接带隙： 计算出(α*hv)2(平方) 4. 画出以hv为X轴，(α*hv)2(平方)为Y轴，画出曲线，在函数曲线单调上升的区域，找到接近直线的地方（即斜率最大的地方），作切线 5. 将切线外推和X轴相交，交点即为带隙宽度 但是我的origin图做出来很有问题，完全没有切线可言，不知道怎么回事，请高手指教，薄膜厚度0.00003cm Wavelength nm.
