The authors have fabricated undoped -channel heterostructure field-effect transistors with nearly ideal drain current-voltage characteristics, using atomic-layer-deposited as the dielectric, and measured their transport properties. At , the densities and mobilities of the two dimensional holes can be tuned up to and , respectively. The variable density high mobility two-dimensional hole system provides a large parameter space for the study of two-dimensional physics.
