Aharonov-casher effect in Bi2Se3 square-ring interferometers.
2011
Electrical control of spin dynamics in Bi2Se3 was investigated in ring-type interferometers. Aharonov-Bohm and Altshuler-Aronov-Spivak resistance oscillations against a magnetic field, and Aharonov-Casher resistance oscillations against the gate voltage were observed in the presence of a Berry phase of pi. A very large tunability of spin precession angle by the gate voltage has been obtained, indicating that Bi2Se3-related materials with strong spin-orbit coupling are promising candidates for constructing novel spintronic devices.
