A novel Raman optical activity instrument operating in the deep ultraviolet spectral region

, 2015
Raman optical activity (ROA) has been exclusively observed in the visible (VIS) and near-infrared (NIR) spectral regions to date. During the last few years, we have designed, constructed and tested the first ROA instrument, operating in the deep ...

Predicting Berborite as Potential Deep-Ultraviolet Nonlinear Optical Crystal from First Principles

, 2020
Following our ab initio nonlinear optical (NLO) materials design guidelines, in this Letter, we discovered a novel type of structure to realize potential deep-ultraviolet (DUV) NLO performance in the classical beryllium borate system. By densely stacking

Performance study of UV micro-LEDs with AlGaN quantum dots and transparent tunnel junction

Next Nanotechnology
It is well known that the size of deep ultraviolet (DUV) micro LED (μLEDs) decreases, although bandwidth improves, the optical power drops sharply, severely limiting the application of DUV μLEDs in optical communication.

Joint intelligent optimization design of the active region and electron blocking layer for AlGaN-based deep ultraviolet LEDs

AIP Advances
Aiming to enhance the internal quantum efficiency (IQE) of AlGaN-based deep ultraviolet light-emitting diodes (DUV LEDs), the active region based on the V-shaped quantum well (QW) and the electron-blocking layer (EBL) structure are jointly optimized ...
