Electrical Control of the Zeeman Spin Splitting in Two-Dimensional Hole Systems
Electrical Control of the Zeeman Spin Splitting in Two-Dimensional Hole Systems
Semiconductor holes with strong spin-orbit coupling allow all-electrical spin control, with broad applications ranging from spintronics to quantum computation. Using a two-dimensional hole system in a gallium arsenide quantum well, we demonstrate a new mechanism of electrically controlling the Zeeman splitting, which is achieved through altering the hole wave vector …
