Long range diffusion noise in platinum micro-wires with metallic adhesion layers

Statistical Mechanics 2009-11-13 v2

Abstract

Voltage fluctuations of Platinum wires hosted by silicon nitride beams were investigated. We considered four variants of the wires: three with an adhesion layer and one with no adhesion layer. We found that the presence of an adhesion layer changes the nature of the power spectrum which is 1/f1/f for wires with no adhesion layers and 1/f3/21/f^{3/2} for wires with an adhesion layer. We attribute the value of the exponent α=3/2\alpha=3/2 to the long range diffusion of hydrogen originating from adhesion layers that undergo a migration through the Pt wires.
