Abstract

A two-dimensional electron-hole system consisting of light high-mobility electrons with a density of N s = (4–7) × 1010 cm−2 and a mobility of μ n = (4–6) × 105 cm2/V s and heavier low-mobility holes with a density of P s = (0.7–1.6) × 1011 cm−2 and a mobility of μ p = (3–7) × 104 cm2/V s has been discovered in a quantum well based on mercury telluride with the (013) surface orientation. The system exhibits a number of specific magnetotransport properties in both the classical magnetotransport (positive magnetoresistance and alternating Hall effect) and the quantum Hall effect regime. These properties are associated with the coexistence of two-dimensional electrons and holes.
