Abstract:
We have investigated the adsorption of cesium on the Si(100) surface with photoelectron emission microscopy using linearly polarized green laser light. We observe a polarization dependent contrast between the (2 x 1) or (1 x 2) reconstructed terraces. Density-functional calculations reveal the geometric and electronic structure of the Cs/Si(100) surface. The contrast between the (2 x 1) or (1 x 2) reconstructed domains is explained on the basis of dipole selection rules for the photoemission matrix elements.

Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
