RF- Transport through a Hall Bar coupled to microwave resonators.

We present here the Radio frequency transport through a Hall Bar from large filling factors to uptill 2. The Hall Bar is made on GaAs-GaAlAs heterostructure two dimensional electron gas.We experimentally study the impedance of this hall bar at radio frequencies (C-Band [4-8 GHz]) . The Hall Bar has two resonators(metallic planar Coils of gold) in series resonating at 5GHz and having a bandwidth of 450MHz, providing better coupling to the sample at high magnetic fields( large hall resistance- 25.8 kilo?). This info is then used to measure high-frequency (f>>kT) Shot noise from a quantum point contact deposited on top of 2DEG and Dynamical Coulomb Blockade effects are observed. Dwell time effects of charge carriers are probed in these measurements.
