| Abstract | ||
| Nanostructured germanium semiconductor optical properties such as energy gap and refractive indexes as function of particle size were investigated. Single-layer antireflection coatings at a quarter wave thickness at λo in the spectrum range of (400-700 nm ) was theoretically designed,when particle size is between (3.6–80 nm) and (Si) as substrate. MATLAB language programs with version of 7.11.0 were used in this study to describe the reflectance as a function of particle size, refractive indexes, energy gap and the wavelength at normal and oblique incidence angle which are depending on Brus model and Characteristic Matrix theory. The result sowed that the coating design (Air/Nano Ge/Si) showed minimum reflectivity value of (0.1623%) at the incident angle of 0° with wavelength of 550 nm and particle size of (Ps=4.4 nm). | ||
