AlGaN-based materials own direct transition energy bands and wide bandgap and thus can
be used in high-efficiency ultraviolet (UV) emitters and detectors. Over the past two decades …

As demonstrated during the COVID-19 pandemic, advanced deep ultraviolet (DUV) light
sources (200–280 nm), such as AlGaN-based light-emitting diodes (LEDs) show excellence …

Polymer solar cells (PSC) using polymer-fullerene bulk heterojunctions (BHJ) have been
extensively studied due to their promising advantages including low-cost manufacturability …

By means of optical spectroscopy, Kelvin probe, and conductivity measurements, we study
the p-type doping of the donor polymer poly (3-hexylthiophene), P3HT, with the molecular …

Optimization of internal quantum efficiency (IQE) for InGaN quantum wells (QWs) light-
emitting diodes (LEDs) is investigated. Staggered InGaN QWs with large electron-hole …

Ultraviolet laser radiation has been adopted in a wide range of applications as diverse as
water purification, flexible displays, data storage, sterilization, diagnosis and bioagent …

We consider in our work single crystal thin films of Bi 2 Se 3, grown by molecular beam
epitaxy, both with and without Pb doping. Angle-resolved photoemission data demonstrate …

The lighting industry undergoes a revolutionizing transformation with the introduction of III-
nitride semiconductors, and" LEDs" became a household name. The solid-state light source …

The coupling effect between piezoelectric polarization and electrochemical processes
makes possible the engineering of charge-carrier conduction characteristics at the …

Antibacterial clothes play a key role in reducing the spreading threat of bacteria, thus
protecting people's health. In this work, several kinds of fabrics with high antibacterial …
