ABSTRACT Gallium oxide (Ga2O3) is an emerging wide bandgap semiconductor that has
attracted a large amount of interest due to its ultra-large bandgap of 4.8 eV, a high …

Owing to their molecular building blocks, yet highly crystalline nature, metal–organic
frameworks (MOFs) sit at the interface between molecule and material. Their diverse …

The low exposure of active sites and the slow electron transfer rate still restrict the wide
application of the photo-Fenton system of Fe-based photocatalyst in practical water …

Using density functional theory calculations, we analyze the optical absorption properties of
lead (Pb)-free metal halide perovskites (AB2+ X3) and double perovskites (A2B+ B3+ …

Vacancy-ordered double perovskites of the general formula A 2 BX 6 are a family of
perovskite derivatives composed of a face-centered lattice of nearly isolated [BX 6] units with …

Transparent conducting oxides constitute a unique class of materials combining properties
of electrical conductivity and optical transparency in a single material. They are needed for a …

Advances in renewable and sustainable energy technologies critically depend on our ability
to design and realize materials with optimal properties. Materials discovery and design …

The direct optical band gap of semiconductors is traditionally measured by extrapolating the
linear region of the square of the absorption curve to the x-axis, and a variation of this …

The development of high-performance transparent conducting oxides is critical to many
technologies from transparent electronics to solar cells. Whereas n-type transparent …

Ga2O3 is attractive for power devices and solar-blind ultraviolet photodetectors due to its
ultra-wide bandgap, large breakdown field, and favorable stability. However, it is difficult to …
