Atomic Force Microscopy Analysis of the Surface Topography of Graphite Extracted Using the Strong Acid Drip Method
Keywords:
Strong acids, Graphene, Nanometric topography.Abstract
Graphene, a two-dimensional (2D) material with a hexagonal shape in its atomically thin structure,exhibits unique electrical properties and has therefore been used in various electronic devices. Hence, obtaininggraphene by acid means using three strong acids, H2SO4, HNO3, and HCl, proportion (1:2:2/3), understandingthe correlation between the structure and the electrical properties at the nanometric scale is essential. Atomicforce microscopy (AFM) techniques provide the best way to visualize these relationships through
