We have observed a resonance in the real part of the finite frequency diagonal conductivity using microwave absorption measurements in high quality 2D electron systems near integer fillings.
We have measured the diagonal conductivity, sigma(xx), in the microwave regime of an ultrahigh mobility two dimensional electron system.
We present measurements of the real diagonal microwave conductivity of the reentrant insulating quantum Hall phases in the first excited Landau level at temperatures below 50 mK.
Wigner solids in two-dimensional electron systems in high magnetic field B exhibit a striking, microwave or rf resonance, that is understood as a pinning mode.
Our recent broadband microwave and RF spectroscopic measurements of two-dimensional electron systems at Landau level filling v greater than or similar to 1 are reviewed.
The effect of subjecting localized regions (~1 mm long) of a glow discharge in neon to pulses of microwaves was investigated by measuring the changes produced in the discharge current.
T h e microwave t r a n s m i t t e r and receiver units constitute t h e basic building blocks for the T D - 3 radio system.
OPTICAL TECHNIQUES HAVE THE POTENTIAL TO OVERCOME BANDWIDTH AND SPEED LIMITATIONS FOR THE GENERATION OF COMPLEX MODULATED MICROWAVE SIGNALS.
Optical techniques have the potential to overcome bandwidth and speed limitations for the generation of complex modulated microwave signals.
In this work we address experimentally a number of unresolved issues related to microwave induced resistance oscillations (MIROs) leading to the zero-resistance states observed recently on 2D elect
