Nanostructured photocathodes for infrared photodetectors and photovoltaics

Are nanostructures suitable for wide-band photodetectors?

In such a way, we discussed the most recent developments on IR detectors using InAs and PbS quantum dot nanostructures. Overall, this review gives clear view on the development of suitable device architecture under prominent nanostructures to tune the photodetector performance from UV to IR spectral regions for wide-band photodetectors.

Can inorganic nanostructures be used for infrared photodetection?

This article reviews the state-of-the-art research of low-dimensional inorganic nanostructures and their application for infrared photodetection. Thanks to nano-structuring, a narrow bandgap, hybrid systems, surface-plasmon resonance, and doping, many common semiconductors have the potential to be used for infrared detection.

Why are nanostructured materials attracting interest in photodetectors?

The nanostructured materials and architectures are attracting extensive interests in photodetectors in view of the potential benefits from confined light-matter interaction, fast carrier dynamics and ultrahigh photoconductive gains.

What are the different types of nanowire-based infrared photodetectors?

The current research of nanowire-based infrared photodetectors can be mainly divided into three categories: single nanowire, [7, 43, 64] ensemble (random) nanowire, [65 - 67] and ensemble (ordered) nanowire array [6, 26, 27] based photodetectors.

Can nanostructured plasmonic metamaterials be used for infrared photodetection?

The recent achievements in exploring nanostructured plasmonic metamaterials for the intriguing subwavelength photon confinement and waveguides in devices are also surveyed considering their importance in device integration. An outlook of infrared photodetection is given in the end as a guideline for this vigorous field.
