Abstract

The cathodoluminescence (CL) of GaN crystallites with and without surface oxide layers is reported. The CL intensity of the coated GaN crystallites is higher than that of the crystallites without oxide layers although the shapes of the coated GaN crystallites are similar to those of uncoated GaN crystallites. The surface coating with gallium oxide is effective for the reduction of surface recombination in GaN crystallites. Electroluminescent devices (ELDs) using GaN crystallites covered with gallium oxides were fabricated. UV light emission was observed from the GaN‐based ELDs at RT.

The combination of photolithography, e-beam lithography and atomic force microscopy (AFM) techniques is used for local oxidation of hydrogen terminated surfaces with a resolution down to % 10 nm. Lithographic masks are used for treatment in oxygen plasma. In AFM the surface can be oxidized directly

## Abstract In this work, three different sets of processing techniques (wet, dry, and combined treatments) were utilized to modify the surfaces of indium‐tin oxide (ITO) substrates for polymer electroluminescent devices (PELDs), and the influence of surface treatments on the surface properties of
