In this paper we study the linear and nonlinear intersubband optical properties of a nanocrystalline singly charged Si semiconductor quantum dot surrounded by an amorphous matrix of silicon dioxide, silicon nitride, and silicon carbide. A finite barrier height is considered at the interface of the dot and matrix. We also consider the effect of self-energy associated with the surface

Silicon carbide (SiC) is regarded as a semiconductor and thus characterized mainly for its electrical conductivity. However, SiC does exhibit significant electrical resistance at low aient temperatures and represents a possible dielectric insulator. In this paper, the dielectric properties of the β-SiC nanopowders were examined by X-ray diffraction and dielectric spectroscopy within the

12/5/2016· Dielectrics in Electric Fields explores the influence of electric fields on dielectric—i.e., non-conducting or insulating—materials, examining the distinctive behaviors of these materials through well-established principles of physics and engineering. Featuring five new chapters, nearly 200 new figures, and more than 800 new citations, this fully updated and significantly expanded Second
When 3C-SiC is grown on a silicon (111) substrate, this produces the ideal template for hexagonal GaN, due to a lattice mismatch of approximately 3.5 percent at the SiC-silicon interface. Reducing mismatch between GaN and silicon is valued highly, because it holds the key to reducing the intrinsic defects found in GaN when this material is grown on highly mismatch substrates, such as silicon

The dielectric constant of a measured test film stacking layer composite dual layer diffusion barrier for 65 nm and 45 nm technology has been studied. The dielectric constant of α-SiCN:H film deposited by using 4MS (5.68) is higher than by using 3MS (4.81).
For (331 K) the dielectric constant in Figure 2(a) exhibits a marginal relaxation, which shows up as a smeared out step at low temperatures. This also gives rise to a broadened in (e.g., 210 K for 16 Hz) and a slight reduction of the conductivity, for example, for 16 Hz between 150 K and 200 K, depicted in Figures 2(b) and 2(c), respectively.

Silicon-based power transistors are reaching limits of operating frequency, breakdown voltage and power density in the power electronics industry and GaN’s performance is beginning to shine. By no means is silicon going extinct, but energy requirements are continuing to increase, thereby requiring new methods and materials to be investigated/used to meet these demands.
