Abstract:
A plasmonic detector is described which can resonantly enhance the performance of infrared detectors. More specifically, the disclosure is directed to enhancing the quantum efficiency of semiconductor infrared detectors by increasing coupling to the incident radiation field as a result of resonant coupling to surface plasma waves supported by the metal/semiconductor interface, without impacting the dark current of the device, resulting in an improved detectivity over the surface plasma wave spectral bandwidth.
Abstract:
Provided is a method for growing a nanowire, including: providing a substrate with a base portion having a first surface and at least one support structure extending above or below the first surface; forming a dielectric coating on the at least one support structure; forming a photoresist coating over the substrate; forming a metal coating over at least a portion of the dielectric coating; removing a portion of the dielectric coating to expose a surface of the at least one support structure; removing a portion of the at least one support structure to form a nanowire growth surface; growing at least one nanowire on the nanowire growth surface of a corresponding one of the at least one support structure, wherein the nanowire comprises a root end attached to the growth surface and an opposing, free end extending from the root end; and elastically bending the at least one nanowire.
