The CdTe/CdS interface has been investigated by photoemission and low energ
y electron diffraction. The growth of CdS on single crystalline CdTe substr
ates at elevated temperatures proceeds with the conservation of rotational
symmetry. Initial results for the dependence of the band alignment on the c
rystallographic orientation based on calibrated core level binding energies
are presented. (C) 2001 Elsevier Science B.V. All rights reserved.
