Probing 2D Physics with Microwave

Abstract

Microwave absorption, using the co-planar waveguide configuration that we developed earlier, was employed to investigate electron dynamics of the high mobility 2D charge carriers in GaAs/AlxGa1-xAs heterostructures. Three experiments were carried out: (1) Dynamic response of composite fermions in an anti-dot lattice (2) Observation of microwave induced cyclotron harmonics, and (3) Investigation of pinning of the Wigner crystal and measurement of the crystal correlation lengths as a function of carrier density.
