Study of graphene-like layer deposition at interfaces

Graphene are in focus of scientific interests due to its unique optical, thermal and electrical properties. In this paper we present a method suitable for the in-situ monitoring of the deposition processes of graphene-like layers on gold surfaces. By using surface plasmon resonance spectroscopy SPR as a high surface sensitive method we successfully illustrate both the time-resolved monitoring of the deposition process and the optical properties. Furthermore we studied the influence of a pulsed UV-laser on the deposition process. With SPR imaging we attained a resolution for layer thickness in the sub nanometer range. So we were able to analyze the homogeneity of the deposition process.
