Simulation of Islands and Vacancy Structures for Si/Ge-covered Si(001) Using a Hybrid MC-MD Algorithm

A classical hybrid MC-MD algorithm is applied to study physically interesting phenomena, such as island stability and formation of dimer-vacancy structures, on Si/Ge-covered Si(001). The method introduces collective moves into the standard MC algorithm to allow the system to escape from metastable states. Simulation results are found to be in good qualitative agreement with experiments.

Computer Simulation Studies in Condensed Matter Physics: An Introduction

The fundamental role played by computer simulation studies in many areas of condensed matter physics is now well accepted. The “status report” on this topic contained in this volume is the result of presentations and discussion that took place during the 16th Annual Workshop at the Center for Simulational Physics. The texts of both longer, invited presentations as well as a number of contributed papers are included. The reader will find that the scope of simulational/computational studies is broad and that substantial potential for cross-fertilization of methods between different sub-fields exists.

New Directions: An Introduction

This year’s workshop includes papers which deal with a number of different rapidly developing aspects of computer simulations in condensed matter physics. The invited talks include rather long papers with some pedagogical content and at the end of this volume we present a few shorter, contributed papers which represent very recent research results.
