內容摘要:  
Using first principle approach we investigate shot noise and current induced effects, such as local heating, inelastic current, and current induced force in nanoscale junctions. We study those effects in atomic wires and molecular junctions in the framework of density functional theory. In such a small system, transport properties of nano junction strongly depend on individual atom and detail electronic structures. We will compare some of our results with available experimental data.
