Growth and microindentation analysis of pure and doped Sb2Se3 crystals
Sb2Se3 microindentation energy gap doping
2010/4/8
Pure and doped antimony selenide (Sb2Se3, Sb2Se2.8Te0.2, and Sb2Se2.6Te0.4) crystals have been grown from melt by the Bridgman Stockbarger method. X-ray powder diffraction analysis was carried out to ...
Studies on the Opto-Electronic Constants of Alkali-Halide Crystals
Refractive index energy gap electronegativity electronic polarizability alkali-halides
2010/4/12
In this presentation, the correlation between refractive index n of alkali-halide crystals and both energy band gap Eg and Pauling's electronegativity difference D x have been studied. The following r...
Weak Localization in Disordered Two-dimensional Crystals with Half-Filled Band
Weak Localization Disordered Two-dimensional Crystals Half-Filled Band
2010/4/16
Effect of subtitutional impurities on electron localization in two dimensional (2D) lattice near the middle of the band is studied. Calculation of density of the electronic states, r (\varepsilon ), i...
