Single-crystal atomic layer deposited Y2O3 on GaAs(001)  growth, structural, and electrical characterization
First demonstration of single-crystal atomic layer deposited oxide on GaAs(001). Attainment of very thin single crystal ALD-Y2O3 1nm thick on GaAs(001). Thin ALD-Y2O3 film with excellent crystallinity having FWHM of ?0.033. Lowest frequency dispersion ever achieved in the ALD-oxides on n-type GaAs(001). Thermodynamic stability at high temperatures of 900C.
