Disorder Effects on Tunneling Junctions
This paper illustrates statistical properties of tunnel currents flowing through metalinsulator- metal tunnel junctions. A direct experiment performed on a metal-oxide junction shows that the tunnel current follows broad statistical distributions extending over more than 4 orders of magnitude. A simple lognormal law is proposed to explain the properties of currents flowing through tunnel junctions.
