Investigation of the growth regimes in GaSbBi alloys with high Bi content by combinatorial MBE

    Research output: Other conference contributionAbstractScientific

    Abstract

    We investigate the relationship between growth parameters and resulting material properties of high Bi content (0 < x < 14.8%) GaSb(1-x)Bi(x) alloys using a combinatorial approach. In this approach, we utilize the non-uniformity of the MBE sources using stationary (non-rotating substrate) growth, which allows to map a wide range of flux conditions in a single growth run. In particular, we show that the Sb/Ga flux ratio is key in controlling Bi incorporation and crystalline/surface quality, and discuss the growth window where these properties are optimal. We further explore this window and study the influence of the growth temperature, Bi-flux, and growth rate.
