✦ Synopsis

The rotational anisotropy in the optical second harmonic response from flat and stepped Ag electrode surfaces biased in an electrolyte solution have been examined. Compared to the flat Ag( 111) surface, the stepped surfaces show a pronounced effect due to the lowering of the surface symmetry. The results are interpreted in terms of a pseudo mirror plane at these steps.

Optical second-harmonic generation has been used to follow in situ the growth of thin Ag Ðlms deposited on Si(111) under various substrate conditions and temperatures. This method is particularly sensitive to the microscopic structure of the deposited Ag Ðlms. Thus, island formation is found to enha

The third-order susceptibility of a charged metal surface can strongly affect the efficiency for optical second harmonic generation from that metal. We present preliminary evidence for this effect on a polycrystalline Ni electrode probed at a fundamental wavelength of 1064 nm. The surface charge is
