Pressure dependence of the refractive index of diamond, cubic silicon carbide and cubic boron nitride

Investigation of the optical properties of Mg(OH)2 and MgO nanostructures obtained by microwave-assisted methods

“…The refractive index n is a very important physical parameter related to the microscopic atomic interactions. From theoretical view point, there are basically two different approaches of viewing this subject: the refractive index will be related to the density and the local polarizability of these entities [35]. Consequently, many attempts have been made in order to relate the refractive index and the energy gap E g through simple relationships [36][37][38].…”

Annealing temperature effect on structural, optical, morphological and electrical properties of CdS/Si(100) nanostructures

“…Theoretically, the two different approaches in viewing this subject are the (10) αhv = A hv − E g n (11) K = α /4π refractive index related to density, and the local polarizability of these entities (Balzaretti and da Jornad 1996). On the other hand, the crystalline structure represented by a delocalized picture, n will be closely related to the energy band structure of the material, complicated quantum mechanical analysis requirements and the obtained results.…”

Ultrasonic effect on optical, structural, topographical and morphological studies of Cu 2 CdSnS 4 quaternary alloy nanostructures

“…Theoretically, the refractive index is related to the density and the local polarizability of these entities [24]. Many simple relationships between refractive index n and the energy gap E g have been attempted [25][26][27][28][29][30][31][32].…”
