Silicon (Si) has a Diamond crystal structure on a face-centered cubic (fcc) lattice as shown in Fig. 1(a). It is cheaper compared to exotic materials such as gallium arsenide (GaAs) and lithium niobate (LiNbO3). In addition, silicon has an energy gap of around 1.1 eV (Chelikowsky ...
crystal, as crystal diameter, crystal length, growth rate, and cooling rate were increased. The diamond cubic lattice can be modeled as two interpenetrating face-centered cubic (FCC) lattices. If dislocations are present, their motion occurs in the 12 slip systems for FCC, along the close-...
When the second nearest neighbors are arranged on a face center cubic (FCC) lattice (or hexagonal close packed (HCP) lat- tice), the central silicon atom was marked as c-Si (or twin-Si) atom, otherwise it was marked as a-Si atom. Density functional theory (DFT) calculations All DFT ...
For example, Federal Communications Commission (FCC) Part 68 governs the interface requirements for telephones in the United States. However, the interface requirements world wide are not standardized, and thus, in countries other than the United States the applicable standards may include the TBR21,...

The high-resolution image of a NP in the [001] zone axis exhibits the typical square pattern of the cubic structure of this phase (Figure 1c,d). Let us note, however, that the β-phase thus defined differs from the α-phase (solid solution in fcc Cu) by only small atomic ...
[1973]), the high-temperature γ-loop extends from 912°C to 1394°C, with the tip at 2.5% Si. Thus one of the benefits of Si addition to Fe is to enable high-temperature heat treatment for grain-orientation control without the deleterious effect of the α–γ (bcc-fcc) phase ...
