Abstract

Ballistic carrier transport is studied in real space in tungsten single crystals using carrier excitation by laser light. So-called electron focusing caustics, singularities of the carrier flux in specific directions, have been investigated systematically for crystals in three different orientations. The influence of magnetic fields B on the focusing patterns has been studied for different field orientations. Sondheimer oscillations periodic in B have been observed. The experimental data can be described by a simple model based on fully ballistic transport. Calculated focusing patterns are in satisfactory agreement with the experiments.
