Direct observation of quantum superconducting fluctuations in an insulating groundstate
N. P. Armitage, R. Crane, G. Sambandamurthy +3
We review our recent measurements of the complex AC conductivity of thin InO_x films studied as a function of magnetic field through the nominal 2D superconductor-insulator transit…

From the magnetic-field-driven transitions to the zero-field transition in two-dimensions
Y. Hanein, D. Shahar, Hadas Shtrikman +3
For more than a decade it was widely accepted that two-dimensional electrons are insulating at zero temperature and at zero magnetic-field. Experimentally it was demonstrated that,…

Microwave Resonance and Carrier-Carrier Interaction in Two-Dimensional Hole Systems at High Magnetic Field
C. -C. Li, J. Yoon, L. W. Engel +3
Microwave frequency conductivity, Re(), of high quality two-dimensional hole systems (2DHS) in a large perpendicular magnetic field (B) is measured with the carrier density…
