Pure silicon is more like an insulator than a conductor, and when external forces are applied (such as applied voltage), it has no ability to change its conductive state. So other elements must be doped into silicon, and the two most important dopants are boron (B) and [...]

IR images reveal that Te inclusions exist in CdZnTe crystal in the form of square, hexagonal and triangular shapes. The density of Te inclusions for sizes above 5 μm sharply varied from 2.27 × 103 cm−2 to 4.52 × 105 cm−2 with a consequent reduction in IR transmittance from ∼60.5% to ∼55% when the Te-rich volume increased [...]
Newly engineered substrates consisting of semiconductor-on-insulator are gaining much attention as starting materials for the subsequent transfer of semiconductor nanomembranes via selective etching of the insulating layer. Germanium-on-insulator (GeOI) substrates are critically important because of the versatile applications of Ge nanomembranes (Ge NMs) toward [...]
