The most important components in most of the electronic products today, such as computers,
mobile phones or digital recorders, are closely related to semiconductor. Semiconductors …

Conventional light-emitting diodes (LEDs) always pursue the high brightness required for
solid-state lighting. However, they always exhibit very low frequency bandwidth of tens MHz …

With the development of GaN‐based optoelectronic devices, the need for p‐GaN contacts
with low resistivity, good thermal stability, and high transparency or reflectivity has become …

Gallium is magnetic and a good conductor of both electricity and heat. There are a few
minerals in which gallium forms a significant part. The main gallium‐bearing mineral is …

We report a void defect in gallium nitride (GaN) and InGaN, revealed by aberration-corrected
scanning transmission electron microscopy (STEM). The voids are pyramids with symmetric …

To identify the individually optimized thermal annealing conditions for reducing the contact
resistivity between highly Ga-doped ZnO (GaZnO) and doped-GaN and for improving the …

We report microstructural characterization of heavily Ga-doped ZnO (GZO) thin films on GaN
and sapphire by aberration-corrected scanning transmission electron microscopy. Growth …

The combined effects of a few mechanisms for emission efficiency enhancement produced
in the overgrowth of the transparent conductor layer of Ga-doped ZnO (GaZnO) on a surface …

We demonstrate a method to improve the light extraction from an LED using photonic crystal
(PhC)-like structures in metal contacts. A patterned metal contact with an array of Silicon …

Ga-doped ZnO (GZO) thin films were deposited on p-GaN as transparent conducting layers
(TCLs) of GaN-based LEDs by radio-frequency (RF) magnetron sputtering. The sputtering …
