Research Abstract |
In this research project, the formation mechanism of electron channeling(EC) contrasts in SEM-BSE(back-scatter electron) images was investigated by examining the influences of EC contrasts to the tilting of specimen and the position of an electron detector. The experimental results revealed that the EC contrasts are explained by the relative relationship between the intensity distribution of primary electron waves and the positions of atomic columns in crystalline specimen. A new procedure for characterization of dislocations was proposed.
