Abstract
A form of optical second-harmonic microscopy has been developed that spatially resolves concentration gradients of surface adsorbates. Surface concentration profiles at submonolayer levels are illuminated with a pulsed laser, and the reflected second-harmonic light is imaged into a photodiode array. Micrometer-scale resolution is obtainable while the surface damage and the spurious chemistry induced by more conventional electron- or ion-based techniques are avoided. We have used this microscopy to monitor the surface diffusion of Sb on Ge(111).
