Introduction Scanning electron microscope (SEM) is a powerful instrument for a high resolution imaging of materials from a various fields of science and industry.
Powder P47 and yttrium aluminium garnet (YAG) single crystal [7] are the most efficient scintillators even if powder material of P47 is suitable only for SE detectors.
Apart from the well known material contrast of the BSE micrographs, other advantages of the BSE detection mode were determined.
The above outlined properties demonstrate that the scintillation BSE detector is an excellent tool for the basic material characterization of both conductive and insulated nanomaterials.

Introduction Since nature is in eternal motion and change, the media, artificial materials or structures inevitably produce various defects and uneven distribution of the formation also give rise to large amounts of heterogeneity, such as small faults, joints, multiple lens, etc., which distribute arbitrarily.
There are different material constantsof two different media.

In addition, the materials will meet heat treatment under technical process.
Zhang[24] et al had found imperfect tape composed with dislocation loops by etch method will appear in InSb materials after annealing at 500°C, and the author thought stress relief leads to the imperfect tape.
This phenomenon also appeared at other kind of material.
