Quantum Monte Carlo Simulation of a Resonant Tunneling Diode Including Phonon Scattering

Kosina H., Nedjalkov M., Selberherr S., Institute for Microelectronics, TU Vienna, AT

A Quantum Monte Carlo (QMC) method taking into account both interference and dissipation effects is presented. The method solves the space-dependent Wigner equation which includes semi-classical scattering via the Boltzmann collision operator. The classical force [...]

Structural and Electronic Properties of Quantum Dot Surfaces

Galli G., Puzder A., Willilamson A.J., Grossman J.C., Pizzagalli L., Lawrence Livermore National Laboratory, US

We report on recent progress in studying the structural, electronic and optical properties of Si and Ge quantum dots, using first principles calculations. We used both ab initio molecular dynamics techniques and quantum Monte Carlo [...]
