Abstract
The temperature dependence of the hole mobilities of AlxGa1−xSb films in the regime
0 x 0.25 has been examined by Van der Pauw–Hall measurements. The films have
been grown by metalorganic chemical vapor deposition on Si–GaAs substrates using
TMAl, TMGa, and TMSb precursors. The mobility decreases sharply when a small
amount of Al in the range 0
