20 Jan 2020 III–V semiconductors are promising candidates for solar water splitting. They indeed offer remarkable photon-to-electron energy conversion The atoms in a semiconductor are materials from either group IV of the periodic table, or from a combination of group III and group V (called III-V semiconductors) The room-temperature thermal conductivity of semiconductor alloys is analyzed using a simplified model of the alloy-disorder scattering. Good agreement is III–V semiconductors: Crystallizing with high degree of stoichiometry, most can be obtained as both n-type and p-type. Many have high carrier mobilities and direct 2.4.

Room-temperature photoluminescence from III-IV-V semiconductor alloys. Massachusetts Institute of Technology in the USA claims significant room-temperature photoluminescence (PL) “for the first time in high-quality III-IV-V alloys grown by metalorganic chemical vapor deposition” [Roger Jia et al, J. Appl. Phys., vol123, p175101, 2018]. III-V compound semiconductor material systems This chapter offers a short overview of the employed material systems and of the epitaxy techniques used for the layer structure growth. Furthermore, the Gunn diode layer structures considered in this dissertation are described.

The peculiar structural, electronic, and optical properties of IV–VI semiconductors as compared to other semiconductor materials are a consequence of the ten valence electrons per atomic pair instead of the eight valence electrons typical for the tetrahedrally bonded group IV, III–V, and II–VI semiconductors. Alloying the III-V and IV-IV sheets leads to III-IV-V nano-composites, such as the BC2N sheet, having a lower band gap than their parent III-V counterparts while having higher cohesive energies. Unlike the well known BC2N sheet, the formation energy of the III-IV-V sheets with high Z atomic constituents is much low suggesting in favour of their A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors typically form in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth). This first volume presents the most important data on two groups of semiconductors, the elements of the IVth group of the periodic system and the III-V compounds.
