Additionally, black silicon, which modifies the energy band structure of single-crystal silicon, enables efficient absorption of photon energy in the NIR and ultraviolet (UV) ranges. This makes black silicon useful for photodetectors, night vision cameras, and NIR avalanche photodiodes (APDs). Indium...
Photodesorption and photodiffusion from the faulted half (F) to the unfaulted half (U) of a unit cell gave evidence of being ∼3× more probable than U → F.GuopingJiangandJohnCPolanyiandDuncanRogersSDOSSurface ScienceJiang G, Polanyi JC, Rogers D. Electron and photon irradiation of...
It is shown that the nature of the sub-band-gap photoresponse is determined by the epitaxial growth temperature of the Si:Er layer and is not related to the composition of erbium emission centers. It is found that the absorption of light with photon energies lower than the energy-gap of ...

We report low-temperature (77 K) photoreflectance measurements in two Ge/Ge 0.7 Si 0.3 strained-layer superlattices, in the photon energy range 0.8-1.8 eV. The multiple lines observed in our spectra in this energy region can be consistently explained in terms of quantum confinement of zone-cen...
