A Nondestructive Synchrotron Radiation Photoemission Study of the Band Lineup for Buried GaSb-AlSb Interfaces.
01 January 1987
We investigated the GaSb-AlSb band lineup by using synchrotron- radiation photoemission with tunable surface sensitivity. The results are consistent with a large valence band discontinuity, DELTA E sub v - ~0.4 eV, and in disagreement with the common anion rule.
