Tunability of electrical and thermoelectrical properties of monolayer MoS through oxygen passivation
Swarup Deb, Pritam Bhattacharyya, Poulab Chakrabarti +4
Electric and thermoelectric properties of strictly monolayer MoS films, which are grown using a novel micro-cavity based CVD growth technique, have been studied under diverse e…
Possible effect of collective modes in zero magnetic field transport in an electron-hole bilayer
A. F. Croxall, K. Das Gupta, C. A. Nicoll +4
We report single layer resistivities of 2-dimensional electron and hole gases in an electron-hole bilayer with a 10nm barrier. In a regime where the interlayer interaction is stron…
Anomalous Coulomb drag in electron-hole bilayers
A. F. Croxall, K. Das Gupta, C. A. Nicoll +5
We report Coulomb drag measurements on GaAs-AlGaAs electron-hole bilayers. The two layers are separated by a 10 or 25nm barrier. Below T1K we find two features that a Ferm…
Patterned backgating using single-sided mask aligners: application to density-matched electron-hole bilayers
A. F. Croxall, K. Das Gupta, C. A. Nicoll +4
We report our work on fabricating lithographically aligned patterned backgates on thin (50-60m) \Roman{roman3}-\Roman{roman5} semiconductor samples using {\it single sided mask…
Fabrication of closely spaced, independently contacted Electron-Hole bilayers in GaAs-AlGaAs heterostructures
J. A. Keogh, K. Das Gupta, H. E. Beere +2
We describe a technique to fabricate closely spaced electron-hole bilayers in GaAs-AlGaAs heterostructures. Our technique incorporates a novel method for making shallow contacts to…
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…
