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…

Magnetoresistance and conductivity exponents of quench-condensed ultra-thin films of Bi
K. Das Gupta, G. Sambandamurthy, V. H. S. Moorthy +1
We have studied the magnetoresistance (MR) and evolution of conductivity with thickness of quench-condensed Bismuth films on substrates of various dielectric constants. Our results…
