Study of metal and metal oxides in the matrix of graphite and Graphene using photoacoustic technique

Abstract

We report the study of Graphene, Graphene (GR)+Aluminum (GR +Al), and Graphene +Silver (GR +Ag), Graphite, ZnO, Fe2O3, Al2O3and their mixture with Graphene using time domain pulsed photoacoustic technique where Q-Switched Nd:YAG laser (532nm, 10Hz repetition rate was employed to study the samples and highlight the changes that occur when these samples are subjected to different incident laser energies.
