Abstract
The problem of obtaining localised information from solids by electrons is discussed and arguments in favour of scanning Auger electron microscopy (SAM) and scanning very-low-energy electron microscopy (SLEEM) are given. Examples highlighting the problems of using either of these methods alone are shown which demonstrate the need to combine both techniques. A novel mini-held emission all electrostatic column has been developed for use as the electron probe for a combined SAM/SLEEM system. The column comprises all the lenses and a novel SLEEM detector based on the cathode lens principle. The whole system measures 92 mm in length and fits inside a cylindrical mirror analyser. A series of micrographs demonstrating the principle of the SLEEM detection from a composite sample of Au, Al and C obtained with electron energies over the range 13-5000 eV is given.
