Abstract
The gate voltage dependence of the Rashba effect in a p-type quantum well was investigated by using Shubnikov-de Haas measurements. The GaSb-based p-type quantum well has a large Rashba spin-orbit interaction parameter of 1.71 x 10(-11) eVm for a zero gate voltage and exhibits gate controllability. We also propose a complementary logic device using n- and p-type spin transistors that simultaneously utilize charge and spin currents to improve the signal margin. (C) 2013 Elsevier Ltd.
