abstract

  • Recent experiments on re-emission of radiation and magnetotransport in photoexcited two-dimensional electron systems are theoretically analyzed. These experiments have concluded that there exists a strong correlation between the re-emitted radiation and the radiation-driven current through the sample. We study these remarkable experimental results using the radiation-driven electron orbit model. According to it, two-dimensional electrons under a magnetic field move back and forth driven by radiation. Therefore, they behave as oscillating dipoles re-emitting part of the radiation previously absorbed. Then, this theory would explain in a simple way the experimental results.
