Cyclotron resonance spectroscopy in a high mobility two dimensional electron gas using characteristic matrix methods

Academic Article

Abstract

  • We develop a new characteristic matrix-based method to analyze cyclotron resonance experiments in high mobility two-dimensional electron gas samples where direct interference between primary and satellite reflections has previously limited the frequency resolution. This model is used to simulate experimental data taken using terahertz time-domain spectroscopy that show multiple pulses from the substrate with a separation of 15 ps that directly interfere in the time-domain. We determine a cyclotron dephasing lifetime of 15.1±0.5 ps at 1.5 K and 5.0±0.5 ps at 75 K. © 2012 Optical Society of America.
