(IoP, 2018-04-18)We report magnetotransport studies in thin (<100nm) exfoliated films of CuₓBi₂Se₃ and we detect an unusual electronic transition at low temperatures. Bulk crystals show weak superconductivity with Tc~3.5K and a possible ...
(IEEE, 2018-01-01)The intrinsic gain (Ai), transconductance efficiency (gm/IDS) and cut-off frequency (fT) are analysed for thin film transistors (TFTs) operating in the deep subthreshold region to assess the impact of device variations on ...
Understanding and Controlling Cu-Catalyzed Graphene Nucleation: The Role of Impurities, Roughness, and Oxygen Scavenging (American Chemical Society, 2016-12-27)The mechanism by which Cu catalyst pretreatments control graphene nucleation density in scalable chemical vapor deposition (CVD) is systematically explored. The intrinsic and extrinsic carbon contamination in the Cu foil ...
