Abstract

AbstractSecond harmonic generation in reflection has been used to investigate the crystal properties of silicon carbide surfaces. By using a passively mode‐locked pulsed Nd3+: YAG laser the variation of the crystalline, polycrystalline and amorphous phase of silicon carbide at the surface has been investigated. The method is shown to be a sensitive and practical method to investigate the departure from perfect crystalline order at the surface.
