Electron Transport Through Mesoscopic Closed Loops and Molecular Bridges

Abstract

An emerging tendency of modern material science is to propose and investigate systems containing smaller and smaller structures. These smaller structures approach the so-called mesoscopic or nanoscopic regimes in which quantum effects become much more relevant for the behavior of these materials. This situates mesoscopic physics at the interface of statistical physics and quantum physics. The mesoscopic systems are very much smaller than the large-scale objects and they often have unusual physical and chemical properties. The study of mesoscopic systems provides a clear understanding of the behavior of a material as it goes from a few atoms to large visible and tangible objects.
