Epitaxial thin films of BaSrO as gate dielectric
Electronic properties of mixed BaSr oxides. ? = 21.80.2, interface trap densities 691010eV?1cm?2, CET below 1nm. Negligible capacitancevoltage hystereses smaller than 10mV, low leakage currents. Band offsets of 1eV for both conduction and valence bands. Tuning of flatband voltage by insertion of an Al layer at the metal gate.
