Silicon (Si) and germanium (Ge) have an indirect band gap transitions; however when they are miniaturized to nanometer scale, the energy gap between the highest occupied molecular orbital (HOMO) and the lowest unoccupied ...
When crystals are constructed on a smaller scale (nanometeric scale), the energy gap between the highest occupied molecular orbital and the lowest unoccupied molecular orbital increased. In this thesis, quantum confinement, ...
The increasing interest in optical properties of the composite media is dictated by the fact that small particles, which are randomly embedded in a linear dielectric host matrix, can be manufactured with the help of modern ...
Today the science astronomy for the study of origins and evolutions has at an advancing level both theoretically and observationally. However, there are a number of works for further developments. For example, the data ...
More recent literature reviews point out that most galaxies, especially early type galaxies with Active Galactic Nuclei (AGN), contain Massive Black Holes (MBHs)considered to be comparable to the masses of high redshift ...
The interaction of the solar wind magnetic field with the Earth’s magnetosphere has a great effect on the near-Earth space environment. This space weather interaction further affects human life activities and life on earth. ...

The main objective of this study was to examine the Light bends when it
passes around an edge or through a silt. This bending of light called diffraction.
You can easily demonstrate diffraction using a candle or a small ...
The optical properties of a semiconductor can be defined as any property that involves the interaction between electromagnetic radiation or light and the semiconductor, including absorption, diffraction, polarization, ...
In this thesis, we have analyzed the photon statistic and quadrature fluctuations of the degenerate three level laser coupled to thermal reservoir. We have found that the mean photon number of the system under consideration ...
In this article, we have analyzed the squeezing and statistical properties of the light generated by
