  • The polished cross-section of the diamond thick films deposited by direct current glow discharge plasma was etched by hydrogen microwave plasma. The grain boundaries and the defects in the films have been directly observed using scanning electron microscopy (SEM). It is found that the non-diamond impurities, and the holes normally appear along the grain boundaries; and at high (low) methane flow rate corresponding to the constant hydrogen flow rate, the films consist of high (low) density of grain boundaries with netted texture.
