Abstract:

We investigated charge transport in large-area arrays of vertically-aligned, gallium nitride GaN based core-shell p-I-n PIN diodes. The processed design can potentially produce photodetectors with efficiencies comparable to or better than traditional photomultiplier tubes PMYs with significant reduction in Size, Weight, and Power SWAP. Our approach combines the precision and scability of top-down processing with the enhanced material quality obtained through selective epitaxy to realize these structures. Vertically-aligned, radial core-shell architecture allows for significant defect reduction, strain engineering, polarity controlled growth, and transformative new device designs.
