Demonstration of low forward voltage InGaN-based red LEDs
Here we report InGaN-based red light-emitting diodes (LEDs) grown on ( 2 ¯ 01 ) β-Ga2O3 substrates. AlN/AlGaN strain-compensating layers and hybrid multiple-quantum-well structures were employed to improve the crystalline-quality of the InGaN active ...

Uranium Doped Gallium Nitride Epitaxial Thin Films
Uranium was controllably added to gallium nitride using molecular beam epitaxy. The uranium atoms segregated into vertically oriented regions with higher doping levels. Concentrations up to a few percent were achieved without showing significant degradation in the crystalline quality or optical characteristics. Low electrical resistivity was maintained

High‐Power Single‐Quantum‐Well 376 nm Ultraviolet A Laser with Low‐Threshold Current Density
A 376 nm ultra‐violet A (UV‐A) laser diode is demonstrated using a GaN waveguide and single‐quantum‐well active region to reduce optical loss and structural strain while improving carrier distribution. The device achieves 2.36 W output power, 822.9 mW/A slope efficiency, and 5.89 kA/cm2 threshold current density, showing a promising route toward high ...

Full InGaN red light emitting diodes
The full InGaN structure is used to achieve red light emitting diodes (LEDs). This LED structure is composed of a partly relaxed InGaN pseudo-substrate fabricated by Soitec, namely, InGaNOS, a n-doped buffer layer formed by a set of InxGa1−xN/GaN ...

An InGaN/GaN Superlattice to Enhance the Performance of Green LEDs: Exploring the Role of V-Pits
Despite the fact that an InGaN/GaN superlattice (SL) is useful for enhancing the performance of a GaN-based light-emitting diode (LED), its role in improving the efficiency of green LEDs remains an open question. Here, we investigate the influence of a V-

Multiscale modeling of battery systems combines quantum‐mechanical calculations, atomistic simulations, and mesoscale phase‐field approaches to describe processes spanning from reaction energetics to morphology evolution. Establishing consistent links between these scales remains a key challenge, particularly for the transfer of physical descriptors ...
