(ELSEVIER SCIENCE BV, 2000)We present results of adiabatic bond charge calculations for the Si(001) Bi(2 x 1) surface using electronic and geometric data obtained from ab-initio pseudopotential calculations. The results are compared to those of ...
-
(AMER PHYSICAL SOC, 2007)We have studied the lattice dynamics of the GaAs(001)-beta(2)(2x4) surface by employing two theoretical methods: an ab initio pseudopotential method and a phenomenological adiabatic bond-charge method. Both methods predict ...
-
(AMER PHYSICAL SOC, 2010)We have investigated the structural and electronic properties of lanthanum in the face-centered-cubic (fcc) and double hexagonal-close-packed (dhcp) phases using a generalized gradient approximation of the density functional ...
-
(AMER INST PHYSICS, 2012)We have performed an ab initio study of structural, electronic, vibrational, and superconducting properties of Cr3RhN. The calculations have been carried out by employing the density functional theory, a linear-response ...

Phonons in zinc-blende and wurtzite phases of GaN, AlN, and BN with the adiabatic bond-charge model (AMER PHYSICAL SOC, 2000)The lattice dynamics of the zinc-blende and wurtzite phases of GaN, AlN, and BN is studied using the adiabatic bond-charge model. The resulting phonon spectra for zinc-blende GaN and AIN compare very well with ab initio ...

(AMER INST PHYSICS, 2002)We present results of adiabatic bond-charge model calculations for the vibrational properties of the GaN(110) surface using electronic and structural data obtained from a first-principles pseudopotential method. It is found ...
-
(AMERICAN PHYSICAL SOC, 2002)We have applied the adiabatic bond-charge model within a supercell approach to study the lattice dynamics of group-III nitride (110) surfaces. The structural and electronic information necessary for these calculations is ...
-
(AMER PHYSICAL SOC, 2000)We have studied the phonon dispersion and density-of-states on the (110) surface of LI-VT compounds CdTe, ZnTe, and ZnS in their zinc-blende phase by applying the adiabatic bond charge model. The relaxed surface atomic ...

(ELSEVIER, 2013)In this work, we have presented a new route to produce pure ZnO and composite ZnO-CuO thin films. In the process we have started with pure ZnO thin films and ended up with CuO by doping Cu in various percentages, ranging ...
-
(CANADIAN SCIENCE PUBLISHING, NRC RESEARCH PRESS, 2015)In this study, we consider three independent physical studies and try to combine them to find an interesting result. Ubriaco's q-deformed bosons and Verlinde's entropic gravity studies are taken into account to find the ...
