The ability to control nonclassical light emission from a single quantum emitter by an integrated cavity may unleash new perspectives for photonic applications. However, coupling within circuitry towards creation of the Purcell-enhanced single-photon is elusive due complexity integrating active devices in low-loss circuits. Here we demonstrate hybrid micro-ring resonator (HMRR) coupled with self-assembled dots (QDs) cavity-enhanced deterministic emission. HMRR supports whispering-gallery...
Arsenic is an essential dopant in conventional silicon-based semiconductors and emerging phase-change memory (PCM), yet the detailed functional mechanism still lacking latter. Here, we fabricate chalcogenide-based ovonic threshold switching (OTS) selectors, which are key units for suppressing sneak currents 3D PCM arrays, with various As concentrations. We discovered that incorporation of into GeS brings >100 °C increase crystallization temperature, remarkably improving repeatability...
Abstract Three-dimensional phase change memory (3D PCM), possessing fast-speed, high-density and nonvolatility, has been successfully commercialized as storage class memory.

Abstract Over the past 60 years, three distinct electrical switching behaviors have been discovered in chalcogenides: ovonic threshold switch (OTS), memory (OMS), and phase‐change (PCS). The first two successfully utilized commercialized 3D Xpoint chips, serving as selector cells, respectively. However, relationships among these remain unclear. Here, it is demonstrated that Ge‐Te binary system exhibits mechanisms. Specifically, behavior transforms from PCS‐like to OTS‐like within composition...
Abstract 3D lead‐free hybrid double perovskites exhibit remarkable potential for direct X‐ray detection owing to their strong photon attenuation capabilities, efficient charge mobility, and low‐cost fabrication.
