Weber, Wolfgang and Ganichev, Sergey and Kvon, Z. D. and Belkov, Vassilij and Golub, Leonid and Danilov, Sergey and Weiss, Dieter and Prettl, Wilhelm and Cho, Hyun-Ick (2005) Demonstration of Rashba spin splitting in GaN-based heterostructures. Applied Physics Letters 87, p. 262106.
The circular photogalvanic effect, induced by infrared radiation, has been observed in (0001)-oriented n-GaN low dimensional structures. The photocurrent changes sign upon reversing the radiation helicity demonstrating the existence of spin splitting of the conduction band in k space in this type of materials. The observation suggests the presence of a sizeable Rashba type of spin splitting, caused by the built-in asymmetry at the AlGaN/GaN interface.
