photonic band gapsilicon compounds/ photonic band gapsSiO 2/air structuresout-of-plane band gapsWe explore the possibilities of achieving larger out-of-plane band gaps in two-dimensional silica/air photonic crystals with hexagonal symmetry. By modification of the basic hexagonal unit-cell, we ...
Opening a sizable band gap without degrading its high carrier mobility is as vital for silicene as for graphene to its application as a high-performance field effect transistor (FET). Our density functional theory calculations predict that a band gap is opened in silicene by single-side adsorption...
Examples of indirect band gap semiconductor materials are silicon (Si), germanium (Ge), aluminum arsenide (AlAs) and gallium phosphide (GaP). Because of the reduced absorption coefficients, silicon layers inphotodiodesandphotovoltaic cells, for example, need to be substantially thicker – often hundre...

The energy gap of silicon is 1.14 eV. Find the maximum wavelenth at which silicon starts energy absorption. View Solution The energy gap of silicon is 1.14eV. The maximum wavelength at which silicon will begin absorbing energy is View Solution Knowledge Check The energy gap of silicon is 1.5...
Semiconductor devices have intrinsic mechanical stress due to two separate sources, silicon wafer processing and packaging. This intrinsic stress induces band gap narrowing and consequent degradation of device reliability. In this work, a silicon die that included shallow trench isolation structures was us...

Wide Band Gap semiconductors (WBG or WBGS) are semiconductor materials with relatively large band gaps compared to typical semiconductors. A typical semiconductor such as silicon has a band gap of 1-1.5 electron volts (eV), while a broadband gap material has a band gap of 2-4 eV. In ...
The proposed structure consists of a planar air-hole type photonic crystal in crystalline silicon as the nonlinear background material. A main advantage of proposing the gap-soliton as a signal carrier is that, by operating in the true time-domain, the temporal soliton maintains a stable pulse ...
