(author) Gate-tunable high-mobility InSb/In1?xAlxSb quantum wells (QWs) grown on GaAs substrates are reported. The QW two-dimensional electron gas (2DEG) channel mobility in excess of 200?000?cm2/V?s is measured at T?=?1.8?K. In asymmetrically remote-doped samples with an HfO2 gate dielectric formed by atomic layer deposition, parallel conduction is...
