We study photoluminescence(PL)of SiOx(0 < x < 2)thin films after annealing at temperatures in the range of 700-1100℃ .The SiOx thin films were prepared by evapor
The thermal expansion, Hugoniot state and 300 K isotherm of sodium have been calculated on the basis of: (i) the accurate calculations of OK total energies with
We calculate the contribution of vector meson dominance to deeply inelastic lepton-nucleon scattering in the kinematic region of the HERMES experiment. The resu
The transport properties of underdoped YBa2 Cu3 Ox (YBCO) crystals with x = 6.95, 6.80 and 6.66 were measured and the effect of the pseudogap on the Hall conduc
In situ high pressure x-ray diffraction and electrical resistance experiments on TiB have been carried out by using a diamond anvil cell device. The results rev
We find the correct "angle" operator conjugate to the intrinsic angular momentum of the photon by introducing a suitable representation which involves both left
The energy levels of a positronium negative ion are calculated directly from the Schrodinger equation. After removing the translational and rotational degrees o
The void evolution in α-Al2O3 irradiated by En ≥ 1MeV neutrons of 3× 10 20 cm-2 and post-annealed from 100℃ to 1050℃ has been studied by a positron annihil
