Abstract

GaN and its ternary alloy AlGaN have been investigated as UV detector materials for applications in protein structure studies. Interdigitated metal–semiconductor–metal (MSM) finger photodiodes, with finger spacings/widths of 5 and View the MathML source, were successfully fabricated on six different GaN/AlGaN materials. Current–Voltage (I–V ) characteristics and spectral response measurements were made on completed devices. The results showed negligible difference in performance between the View the MathML source finger spacing/width diode design and the View the MathML source finger spacing/width diode design. Using these results, a 46 channel diode array, with a finger spacing/width of View the MathML source, was successfully fabricated on View the MathML source thick epitaxial GaN. This 46 channel diode array will be used in a protein structure experiment at the Daresbury SRS.
