The atomic structure in metals is characterized by a lattice of positive-charged ions with a moving electron cloud all around. The electron cloud model can explain some properties of metals, such as high thermal and electrical conductivity and their malleability and ductility. Metals are optically ...

After the optimization of the structural parameters with respect to the high group index for a large bandwidth, the lattice constant of 390 nm and the diameter of the holes of 193 nm are chosen, respectively, in our final design. The position of the first row of holes adjacent to the...
By adding silicon dioxide as the third dielectric, oxide thickness serves as a new parameter that influences the band structure. In the case of a PC of Si atoms in air, if silicon is etched to reduce the original atom radius from 0.28α (α=lattice constant) to 0.1α, the band-gap ...
Crystal SystemThe space lattice of Si belongs to the cubic system, and its diamond structure has a lattice constant of a=0.543072 nm (258℃) and Si–Si=0.235 nm. Production MethodsElemental silicon is produced commercially by heating silica with carbon (coke) in an electric furnace using ...
Colloidal semiconductor nanocrystals have attracted attention for cost-effective, solution-based deposition of quantum-confined thin films for optoelectronics. However, two significant challenges must be addressed before practical nanocrystal-based devic

Incorporation of fluorine into the Si--O lattice reduces its dielectric constant due to fluorine's high electronegativity and low polarizability. Incorporation of fluorine into silicon dioxide can also reduce radiation-induced oxide charges, and improve the hot-electron immunity of the dielectric. ...
