Savchenko, M., Bykov, A. A., Shuvaev, A., Bakarov, A. K., Pimenov, A., & Raichev, O. E. (2024). Optical realization of magneto-intersubband oscillations. Applied Physics Letters, 124(16), Article 162104. https://doi.org/10.1063/5.0204388
We report on the optical realization of the magneto-intersubband oscillations that have been measured in the sub-terahertz transmittance of a GaAs quantum well with two subbands occupied. Following their dc analogue, the oscillations are periodic in the inverse magnetic field with the period governed by the subband gap. Their magnitude and polarization dependence accurately follow the presented simplified version of the dynamic magneto-intersubband oscillations equation that naturally combines dc magneto-intersubband oscillations with microwave-induced resistance oscillations. Simultaneously measured photoresistance also reveals its strong sensitivity to the sign of the circular polarization, proving the used theoretical modeling.
