Multilevel Optical Programming of Intrinsic Vacancies in Solution‐Processed MoS2 Films for Retinomorphic Color Differentiation

open access: yesAdvanced Optical Materials, EarlyView.
Solution‐processed MoS2 films with intrinsic sulfur‐vacancy traps are used to integrate light sensing and memory in a simple two‐terminal pixel. Successive optical pulses program persistent, multilevel conductance states, while oxygen exposure enables rapid erasure.

Energy Efficiency Optimization of Distributed Massive MIMO Systems Under Ergodic QoS and Per-RAU Power Constraints

open access: yesIEEE Access, 2019
Under $\textit {ergodic}$ per-user quality-of-service and per-remote antenna unit (RAU) transmit power constraints, we investigate the problem of maximizing energy efficiency (EE) of distributed massive MIMO systems, which is known to be non-convex. To
