INTRINSIC ABSORPTION OF Hg1-xCdx TE
Hg1-xCdxTe禁带以上的本征光吸收

The intrinsic absorption spectra of Hg1-xCdxTe semiconductor with energies above the band gap are presented by analyzing experimental results, Kane theory and some empirical laws. It is found that Anderson's theorical expression derived from the Kane model and Chu et al' s empirical rule obtained from the measured data agree well with the intrinsic optical absorption behaviour of Hg1-xCdxTe bulk thin films. Moreover, the intrinsic absorption of Hg1-xCdxTe epitaxial layer is discussed.
