摘要
We have investigated the valence band offset (DELTA-E(V)) of the CdTe-HgTe heterojunction for three orientations, (100), (110) and (111)B, using in situ x-ray photoelectron spectroscopy. The difference in energy between the Cd 4d and Hg 5d5/2 core levels, DELTA-E(CL), and consequently DELTA-E(V), was found to be independent of surface orientation and the surface structure immediately prior to growth of the uppermost layer. DELTA-E(V) was found to be 0.37 +/- 0.07 eV.
