Silicon crystallized in the usual cubic (diamond) lattice structure has dominated the
electronics industry for more than half a century. However, cubic silicon (Si), germanium …

This tutorial paper focuses on the physical origin of thermal droop, ie, the decrease in the
luminescence of light-emitting diodes (LEDs) induced by increasing temperature. III-nitride …

High-efficiency semiconductor lasers and light-emitting diodes operating in the 3–5 μm mid-
infrared (mid-IR) spectral range are currently of great demand for a wide variety of …

Silver phenylselenolate (AgSePh) is a hybrid organic–inorganic two-dimensional (2D)
semiconductor exhibiting narrow blue emission, in-plane anisotropy, and large exciton …

We report a comparative study of temperature-dependent photoluminescence and structural
dynamics of two perovskite semiconductors, the chalcogenide BaZrS 3 and the halide Cs Pb …

Organic–inorganic hybrid materials present new opportunities for creating low-dimensional
structures with unique light–matter interaction. In this work, we report a chemically robust …

Monolithic integration of silicon-based electronics and photonics could open the door toward
many opportunities including on-chip optical data communication and large-scale …

Photoluminescence (PL) line shapes in InGaN multiple quantum well structures have been
studied experimentally and theoretically between 10 and 300 K. The higher temperature PL …

The relationship between the structure and properties is always a hot topic in the
luminescent material field. In this work, a new phosphor KBa2 (PO3) 5: Eu2+ (KBP: Eu) was …

We report on three-photon excited band edge and trap emission of CdS semiconductor
nanocrystals. While the band edge emission intensity clearly shows a cubic dependence on …
