Olbrich, Peter and Tarasenko, Sergey and Reitmaier, C. and Karch, J. and Plohmann, Daniel and Kvon, Z. D. and Ganichev, Sergey (2009) Observation of orbital circular photogalvanic effect. Physical Review B (PRB) 79, 121302-1-121302-4.
We report on the observation of the circular photogalvanic effect in Si-metal-oxide-semiconductor fieldeffect transistors with inversion channel excited by terahertz radiation. We demonstrate that in spite of the fact that the photocurrent is caused by transfer of the photon angular momentum to free carriers, it is not due to spin orientation but has a pure orbital origin. It results from the ...
