We present the first limits on inelastic electron-scattering dark matter and photon absorption using a prototype SuperCDMS detector having charge resolution of 0.1 electron-hole pairs (CDMS HVeV, 0.93 g CDMS high-voltage device). These electron-recoil significantly improve experimental constraints particles with masses as low 1 MeV/c^{2}. demonstrate sensitivity to photons competitive other leading approaches but substantially less exposure (0.49 d). results scientific potential...
The SuperCDMS experiment is designed to directly detect weakly interacting massive particles (WIMPs) that may constitute the dark matter in our Galaxy. During its operation at Soudan Underground Laboratory, germanium detectors were run CDMSlite mode gather data sets with sensitivity specifically for WIMPs masses ${<}$10 GeV/$c^2$. In this mode, a higher detector-bias voltage applied amplify phonon signals produced by drifting charges. This paper presents studies of experimental noise and...
We report the result of a blinded search for Weakly Interacting Massive Particles (WIMPs) using majority SuperCDMS Soudan dataset. With an exposure 1690 kg days, single candidate event is observed, consistent with expected backgrounds. This analysis (combined previous Ge results) sets upper limit on spin-independent WIMP--nucleon cross section $1.4 \times 10^{-44}$ ($1.0 10^{-44}$) cm$^2$ at 46 GeV/$c^2$. These results set strongest limits WIMP--germanium-nucleus interactions masses $>$12

Recently, Molybdenum Disulphide (MoS <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> ) has emerged as a promising candidate for low-power digital applications. Compared to monolayer (1L) MoS , few-layer (FL-MoS is attractive due its higher density of states (DOS). However, comprehensive study FL-MoS field-effect-transistor (FET) lacking. In this paper, we report high-performance FET with record low contact resistance (~0.8 KΩ.μm) that...
