Room Temperature STM

This Omicron UHV setup allows performing atomically resolved STM topography and spectroscopy measurements at room temperature and less than 10-11 torr. It is especially suited for cross-sectional STM measurements on in-situ cleaved semiconductor multilayer structures. The images show atomically resolved images of a self assembled InAs quantum dot grown on 311B InGaAs and capped by InGaAsSb and a number Mn impurities in GaAs.
