Abstract

We used a high current density focused electron beam to modify a GaAs substrate. To avoid any oxidation or carbon contamination problem, an in-situ electron gun, combined with III-V molecular beam epitaxy (MBE) machine, was used. By changing the substrate temperature and the electron beam dwell time on each spot, different sizes of thermal irradiation marks were created. Fabricated spot-diameters in the sub-micrometer range suggest the possible utilization of this process for novel applications with the MBE growth technique.
