Nanowire Photodetectors and Applications: A Review Study

Aditi Rai; Usha Shukla

Abstract

The utilization of nanowires and nanowire structures as photodetectors is an arising research subject. Novel gadget structures incorporated in single nanowire gadgets are additionally being effectively contemplated and created. Here, general NW-PD ideas are investigated, along with a point-by-point depiction of the actual phenomenon happening in nanowire photoconductors & phototransistors. Low dimensional frameworks like nanotubes and nanowires have intriguing, and technologically valuable, optical and electrical properties. Studies on these frameworks advance our insight on the science at the nanoscale & give the opportunities for creating scaled down electronic and optoelectronics. They consist of a variety of components, including carbon, silicon, germanium, and conducting materials like copper, silver, and gold. Owing to their unique characteristics (such as large surface area, efficient strain relaxation, and effects of quantum confinement), they often provide superior results when compared to other thin-film counterparts and bulk or three-dimensional nanomaterials. Through various synthesis techniques, many additional materials, including metals, semiconductors, and polymers, can be produced as nanowires. A point of view towards future bearings towards the utilization of semi-conductor nanowire photoconductors as intra-chip interconnects, single-photon detectors & picture sensors, have additionally been given.
