We exploit ultrafast extreme-UV angle-resolved photoemission spectroscopy (XUV ARPES) for sensitive studies of non-equilibrium carrier dynamics in MoSe2. The experiments reveal inter-valley scattering and provide first evidence for the observation of band-gap excitons in ARPES.
Sub-50 mV operation of nano-electro-mechanical relays is demonstrated for the first time, enabled by an anti-stiction molecular coating. Specifically, a self-assembled monolayer of perfluorodecyltriethoxysilane (PFDTES) is shown to be effective for reducing the switching hysteresis voltage, without dramatically increasing its ON-state resistance, enabling stable device operation at very low voltages.
Over the last few decades, advances in electronics have fundamentally changed the way we use energy in our everyday life. While the electronic devices have become faster, smarter and compact, the energy consumption for per bit operation have not reduced significantly. With the motivation to reduce energy consumption in electronic systems, we study layered transition metal dichalcogenides (TMDs), which...
