"Spectroscopy of Rashba spin splitting in InSb quantum wells," PHYSICAL REVIEW B 70(15): 155322 DOI: 10.1103/PhysRevB.70.1553221098-0121http://hdl.handle.net/10919/25409We use electron spin resonance in the far infrared to probe the Landau-level spin splitting in symmetric and asymmetric InSb quantum wells. The asymmetric wells exhibit a strong deviation in behavior from the symmetric wells at low magnetic fields with apparent g factors far in excess of the bulk g factor of InSb. These asymmetry-induced shifts in the spin resonance depend on Landau-level index as predicted by the Bychkov-Rashba model. We analyze the shifts to extract values for the Rashba parameter.en-USIn Copyright2-dimensional electron-gasgaas-alxga1-xas heterostructuresinversionasymmetryorbit interactionresonanceinaslayersdependencesubbandsystemPhysicsArticle - Refereedhttp://link.aps.org/doi/10.1103/PhysRevB.70.155322https://doi.org/10.1103/PhysRevB.70.155322
