; 124, 219906 (2006)]} XC functional. The band gap of InGaN alloys as a function of In
content is calculated and a strong bowing at low In content is found, described by bowing …

With the development of human society, environmental problems caused by the use of
traditional fossil energy sources are increasing. Therefore, environment-friendly, renewable …

In an attempt to partially mimic the natural photosynthesis, a process that converts sunlight
into chemical fuel, a novel InGaN/GaN multi-quantum well (MQW) nanowire heterostructures …

We report the characterization of a N-polar InGaN layer deposited by metalorganic vapor-
phase epitaxy on a ScAlMgO 4 (0001)(SAM) substrate without a low-temperature buffer …

Continuous hydrogen generation from water was realized for 110 h using an n-type GaN film
with a NiO cocatalyst. This GaN–NiO photocatalyst exhibits incident photon-to-current …

Hydrogen gas (H 2) and formic acid (HCOOH) are simultaneously generated through direct
water photoelectrolysis and CO 2 reduction, respectively. These processes are …

p-Type do** in wide bandgap and new classes of ultra-wide bandgap materials has long
been a scientific and engineering problem. The challenges arise from the large activation …

Efficient production of H 2 from water without the use of an extra bias or any sacrificial
reagents is possible using a GaN photocatalyst with a NiO cocatalyst. The average energy …

We have improved the InGaN/GaN heterointerface to achieve higher energy conversion
efficiency by replacing a uniform InGaN layer with a graded In-content InGaN layer. Even In …

Photoelectrochemical water splitting is expecting a new energy source to produce hydrogen
from water. The photoilluminated electrode using a uniform semiconductor single crystal has …
