  • Abstract
    A breakthrough in understanding the nature of wafer-bonded interfaces is reported. The DC-behavior of a wafer-bonded heterojunction between In0.53Ga0.47As (InGaAs) and In0.1Ga0.9N (InGaN) is investigated by using a wafer-bonded vertical electron transistor (BAVET) structure with an In0.52Al0.48As (InAlAs) gate-barrier-layer. It is demonstrated that the Fermi-level of the InAlAs layer influences the wafer-bonded-interface properties (WBIP) during the wafer-bonding of InGaAs to InGaN. Specifically, by using a high p-doping in the InAlAs layer, a dramatic improvement in the WBIP and consequently, a high-breakdown for a BAVET is demonstrated.
