The phase stability and site preference of some ternary elements of ThMn12 type rare-earth intermetallic compounds R ( Co , T )12 and R ( Co , T )12 N x are evaluated based on ab initio converted interatomic potentials. The calculated results show that adding either Mo or Mn makes the crystal cohesive energy decrease markedly.

A significant improvement of contact transfer resistance on undoped GaN/AlGaN/AlN (10 A)/GaN high electron mobility transistor (HEMT) structure was demonstrated using a Ta/Ti/Al/Mo/Au metallization scheme compared to a Ti/Al/Mo/Au metallization scheme.

Study on the cooperativity of hydrogen bonds betweenH2YandHX(X=F,Cl,Br;Y=O,S,Se)
Journal of Theoretical and Computational Chemistry, 2014The structure characteristics, interaction energies, cooperative energies of the complexes between chalcogen hydrides ( H2Y ) and halogen hydrides (HX) have been studied theoretically at the MP2 level with aug-cc-pVTZ basis set in this paper. The conclusions show that there are strong interactions between H2Y and HX.

MAGNETOPHONON RESONANCE IN MnxCdyHg1-x-yTe
International Journal of Modern Physics B, 2007The aim of this work is to analyze the band-structure parameters of Mn x Cd y Hg 1- x - y Te (MMCT) alloys by means of Magnetophonon Resonance (MPR) and to compare that obtained for Zn x Cd y Hg 1- x - y Te (ZMCT). MPR was observed for two samples of Mn x Cd y Hg 1- x - y Te (MMCT) (I- x =0.095 and y =0.09, II-0.04 and y =0.19).

DEPOSITION OF M—C (M = Cr, Mn, Fe) FILMS BY MAGNETRON SPUTTERING
Modern Physics Letters B, 2005Thin films of M — C ( M = Cr , Mn , Fe ) have been deposited on silicon substrates by magnetron sputtering. It was found that interdiffusion between carbide films and silicon substrates occurred for Mn — C/Si and Fe — C/Si samples. The hardness and elastic modulus of the Cr — C films were around 16 ± 1 GPa and 210 ± 21 GPa , respectively.

MEASUREMENT OF R = B(t→Wb)/B(t→Wq) AT DØ
International Journal of Modern Physics A, 2005A measurement of the ratio of branching fractions, R = B(t→Wb)/B(t→Wq), with q being any quark with I3 = -1/2 and Q = -1/3, is presented. This analysis considers samples of single- and double-tagged lepton+jets events obtained with the DØ detector, corresponding to integrated luminosities of 169 pb-1 and 158 pb-1, respectively in the e+jets and μ+jets

THERMODYNAMIC PROPERTIES OF MC (M = V, Nb, Ta): FIRST-PRINCIPLES CALCULATIONS
Modern Physics Letters B, 2013Through the quasi-harmonic Debye model, the pressure and temperature dependences of linear expansion coefficient, bulk modulus, Debye temperature and heat capacity have been investigated. The calculated thermodynamic properties were compared with experimental data and satisfactory agreement is reached.

CALCULATED STRUCTURAL AND ELASTIC PROPERTIES OF M2InC(M=Sc, Ti, V, Zr, Nb, Hf, Ta)
Modern Physics Letters B, 2008Using ab initio calculations, we have studied the structural and elastic properties of M 2 InC , with M = Sc , Ti , V , Zr , Nb , Hf and Ta . Geometrical optimization of the unit cell is in agreement with the available experimental data. We have observed a quadratic dependence of the lattice parameters versus the applied pressure.

Superconducting Properties of Bi-Sr-Ca-Cu-O Crystallized Glass
International Journal of Modern Physics B, 1999This paper reports the crystallization and superconducting properties of Bi 4 Sr 3 Ca 3 Cu 4 O x glass-ceramics. The glass was prepared using the conventional melt-quenching method. X-ray diffraction pattern has shown that the annealing at temperature of 800°C converted the glass into glass-ceramics with Bi 2 Sr 2 CaCu 2 O x superconducting phase ...
