Abstract

Second harmonic generation was measured in porous silicon superlattices surface which were made by changing and anodization current density and the anodization time periodically in the process of obtaining porous silicon. The technique of second harmonic generation is used as a probe to the surface of porous silicon superlattice by using Nd:YAG laser. We have investigated the surface structure and nonlinear-optics properties of porous silicon superlattice.

전류밀도와 에칭시간을 변화시키면서 제작된 다공질 규소 초격자의 표면에서 Nd:YAG 레이저의 제2 고조파를 발생시켰다. 이로부터 대칭구조가 바뀌고 유전율이 상승됨이 관측되었다.
