摘要：

We present the experimental results obtained by angular resolved photoemission on HgTe monocrystals, for a photon energy of 23 eV. The results are compared with other experiments on Cd0.6Hg0.4Te, obtained under the same experimental conditions, and a common scheme is proposed for the emission of the HgTe-CdTe mixed compounds. We computed theoretical emission spectra, using the tight-binding model and show that emissions originate mostly from bulk ''Tep'' orbitals, with a minor component due to umklapp processes. Surface states were not observed at the top of the valence band (near Gamma), as previously reported for CdTe.
