摘要: The microstructure of porous silicon layers has been studied by means x‐ray diffraction. Using a double‐crystal diffractometer, the observed diffraction patterns give directly mismatch between lattice parameters and substrate, curvature various samples obtained in different conditions. From measurements with same experimental set‐up, but larger scan range, broad diffuse bumps produced pore structure have observed. This new feature allows us to obtain structural informations on nondestructive way. In particular, we anisotropic pattern showing preferential elongation pores perpendicular (100) surface.
