Effect of Shot noise in the presence of ferromagnetic exchange potential on the surface of topological insulators
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2013, Vol 6, Issue 9
Abstract
In this paper we investigate the Fano factor of an F|N|F junction in clean limit in the present of ferromagnetic exchange potential. Fano factor shows an oscillatory behavior due to coherent interference of Dirac fermions which transported and reflected by double interfaces. This behavior is signature of Dirac fermions in topological insulator.
