摘要：

We demonstrate the application of optoelectronically generated terahertz electromagnetic transients to real-time detection of coherent oscillations by free electrons in modulation doped semiconductor heterostructures, due to the cyclotron resonance. The damping of these oscillations gives a direct measure of the electron dephasing which can be compared with scattering rates obtained from dc transport measurements. © 1994 American Institute of Physics.
