First-principles plane-wave pseudopotential calculations of the electron structure and energetics of the interfaces between the (0 0 1) surfaces of ferromagnetic fcc Co and TiC are reported. A detailed comparison with the case of the paramagnetic Co(

Using a Boltzmann-like kinetic equation derived in the semiclassical approximation for the partial Wigner distribution function, we determine the ac admittance of a two-dimensional quantum point contact (QPC) for applied ac fields in the frequency ra

We present new results on the a.c. transport of electrons moving through a two-dimensional (2D) semicondutor quantum point contact (QPC). We concentrate our attention on the characteristic properties of the high frequency admittance (ω ≈ 0 – 50G

The authors calculate the a.c.-admittance of a two dimensional quantum point contact (QPC) using a Boltzmann-like kinetic equation derived for the partial Wigner distribution function. An integral equation for a potential inside a QPC is solved numer

A number of important issues raised by brazing technologies and recent wetting experiments with liquid metals on TiC and TiN are analyzed at the microscopic level, using first-principles density-functional computational experiments. The large variati

With the purpose to understand the fundamental difference between two industrially important classes of hard materials, WC-Co cemented carbides and TiC-Co cermets, we do a comparative study of Co/WC and Co/TiC interface adhesion. Using first-principl

The energetics and the electronic structure of fcc Co(001)/TiC(001) and Co(001)/TiN(001) interfaces, which are of much practical importance in the sintering of hardmetals, are investigated by means of first-principles density-functional calculations,

By means of first-principles computational experiments, the microscopic mechanism of metal-carbide adhesion is revealed. Density-functional-theory results for the Co $/$TiC(001) interface show the interface bonding to be dominated by Co-C bonds. The

We have calculated the admittance of a two-dimensional quantum point contact (QPC) using a novel variant of the Wigner distribution function (WDF) formalism. In the semiclassical approximation, a Boltzman-like equation is derived for the partial WDF
