Electric field inversion asymmetry: Rashba and Stark effects for holes in resonant tunneling devices
H. B. de Carvalho, M. J. S. P. Brasil, V. Lopez-Richard +7
We report experimental evidence of excitonic spin-splitting, in addition to the conventional Zeeman effect, produced by a combination of the Rashba spin-orbit interaction, Stark sh…
