Gallium phosphide (GaP) is a polycrystalline compound semiconductor that appears pale orange and has an indirect band gap of 2.26 eV. Single crystal wafers that are not doped have a clear orange color ...

Researchers have identified novel 2D wide-band-gap semiconductors with high stabilities, namely monolayer arsenene and antimonene. These materials are indirect wide-band-gap semiconductors, and under ...

In direct-gap semiconductors the crystal momentum of electrons in the valence and conduction bands match. By contrast, electrons in the conduction band of indirect-gap semiconductors such as silicon ...

Researchers have demonstrated that by using a semiconductor with flexible bonds, the material can be molded into various ...

The materials go from being indirect band-gap semiconductors in the bulk, to direct band-gap semiconductors when scaled down to monolayer thickness. These monolayers efficiently absorb and emit light, ...

The semiconductor has an “indirect” electronic band gap, which means that electronic transitions between the material’s valence and conduction bands involve vibrations in the crystal lattice. As a ...
