In comparison to conventional material matrices (bulks, films, polymers, etc.), nanohybrids represent a wider range of useful materials. They are composed of one or more low-dimensional semiconductor nanostructures, such as quantum dots, nanowires, and nanotubes, as well as 2D atomic materials (graphene, transition-metal dichalcogenides, etc.), interfaced with one another.
Nanohybrids are characterised by heterojunction interfaces, which are essential for enabling the synergistic coupling of constituent materials with various capabilities and producing materials with superior electrical, optoelectronic, and mechanical properties.
As a result, nanohybrids provide new possibilities for designing optoelectronic devices with amazing performance in addition to their advantages of being inexpensive, plentiful, flexible, and lightweight.
Here are some recent developments in using novel optoelectronic nanohybrids and comprehending the underlying physics to create competitive high-performance optoelectronic nanohybrids for various optoelectronic applications.
The significance of controlling the heterojunction interfaces and multiscale optoelectronic processes of light absorption, exciton dissociation, photocarrier transfer, and transport from atomic to device scales, as well as how this control impacts the photodetector performance, are revealed using nanohybrid photodetectors as an example.
The Global Nanohybrid Photodetector market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
A brand-new uncooled MWCNT/Cyt C heterojunction Nanohybrid Photodetector has been demonstrated. An amazing NIR responsivity up to 0.30 A W1 at ambient temperature is produced by the high-effective exciton dissociation resulting from the heterojunction at the interface of MWCNT (donor) and Cyt c (acceptor).
This value is one to three orders of magnitude better than that reported for Nanohybrid Photodetector that only use CNT, and it is attributed to the crucial role that interface heterojunctions play in facilitating exciton dissociation to photocurrent and the combination of effective charge transport of CNT (holes) and Cyt c (electrons).
As a result, on MWCNT/Cyt c heterojunction nanohybrid Photodetector , high EQE up to 38.2% has been attained, which represents a significant improvement by two orders of magnitude over the MWCNT only IR detectors.
