| When light reflects from a material, the reflected wave normally oscillates at the same frequency as in the incident wave. When an intense pulse of light strikes a material, however, it can cause the electrons in the material to oscillate at twice or three times the frequency of the incident wave, and these second-harmonic and third-harmonic oscillations give rise to beams of light at twice and three times the frequency of the incident wave. These beams may be generated preferentially at the surface, leading to noninvasive surface-specific probes, but it is difficult to separate the surface and bulk contributions to harmonic generation. I fabricate crystal silicon films with thicknesses varying from 200 nm down to a few nanometers to separate these contributions to assess the surface selectivity of harmonic generation. |
