The observation of anisotropic scattering of laser light at oblique incidence on a porous silicon layer was presented. The vertical wall of the pores of the porous silicon led to conical scattering events and to optical anisotropy. It was found that the position of the external and internal rings allows a very simple and direct measurement of the anisotropy parameter of the porous silicon layer.

Abstract
The observation of anisotropic scattering of laser light at oblique incidence on a porous silicon layer was presented. The vertical wall of the pores of the porous silicon led to conical scattering events and to optical anisotropy. It was found that the position of the external and internal rings allows a very simple and direct measurement of the anisotropy parameter of the porous silicon layer.File in questo prodotto:
