Abstract

Growing a heterostructure on a conductive substrate, the channel carrier density can be controlled by an applied gate voltage to the substrate. We made InAs/AlGaSb single-quantum wells using n- and p-type InAs substrates as a back-gate. The devices perform well and the gate-leakage characteristics are better for the n-type substrates than for the p-type substrates.
