For II-VI semiconductors, we find that p-d repulsion and hybridization (i) lower the band gaps, (ii) alter the sign of the crystal-field splitting, (iii) reduce the spin-orbit splitting, (iv) change the valence band offset between common-anion semiconductors, and (v) increase the equilibrium lattice parameters, p-d repulsion is also shown to be responsible for the anomalously small band gaps
Next in importance to the elemental semiconductor Si, we have the III-V compound semiconductors obtained by combining group III elements (essentially Al, Ga, In) with group V elements (essentially N, P , As, Sb). This gives us 12 possible combinations; the most …
The structure of such hybrid cell comprises of an organic active material (p-type) deposited by coating, printing or spraying technique on the surface Heterostructures of Superconductors, III-V Semiconductors, and Magnetic Insulators Semiconductor-superconductor heterostructures are a promising platform to build topological quantum bits that could be more stable and scalable than competing technologies [1]. The main purpose of this book is to provide a comprehensive treatment of the materials aspects of group-IV, III-V and II-VI semiconductor alloys used in various electronic and optoelectronic devices. The topics covered in this book include the structural, thermal, mechanical, lattice vibronic, electronic, optical and carrier transport properties of such semiconductor alloys. Group IV semiconductors lie at the heart of many electronic and photovoltaic devices. Issues associated with bulk silicon continue to be important, but substantial fundamental challenges also exist for other group IV bulk materials and associated alloys, nanostructures, nanocomposites, thin/thick films and heterostructures.

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 constitu …
GaAs is known as a III-IV intrinsic semiconductor. Ga has 3 electrons in its outermost shell, and As has 5.

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. All data were compiled from information on about 2500 pages in various volumes of the New Series of Landolt-Bornstein. 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.

Thiol-stabilized and hot injection methods are widely used [94]. Numerous aqueous and organic media-based approaches have been developed to synthesize CdS, CdSe, and CdTe NPs. This is a dummy description. Description. The main purpose of this book is to provide a comprehensive treatment of the materials aspects of group-IV, III−V and II−VI semiconductor alloys used in various electronic and optoelectronic devices.
