Abstract

Voltage fluctuations of platinum wires hosted by silicon nitride beams were investigated. The authors considered four variants of the wires: three with an adhesion layer and one without an adhesion layer. They found that the presence of an adhesion layer changes the nature of the power spectrum which is 1/f for wires with no adhesion layers and 1/f^{3/2} for wires with an adhesion layer. They attribute the value of the exponent \alpha=3/2 found in wires with adhesion layers to the long range diffusion of oxygen atoms along the interface between the adhesion layer and the platinum layer.
