Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

open access: yesAdvanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Multifunctional Micro/Nano-Engineered Solar Thermal Receivers

open access: yes, 2021
Solar thermal receivers/collectors are designed to absorb as much sunlight as possible (e.g. increasing energy inputs) while minimizing heat loss and pumping energy (e.g. reducing energy losses). While nanofluid-based receivers have been proposed as an elegant solution for increasing energy inputs, only half the challenge for overall performance has ...

Zwitterionic Self‐Assembled Monolayer for Simultaneous Noise Suppression and Hole Extraction in High‐Performance Near‐Infrared Organic Photodetectors

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a new hole transporting material (HTM) mechanism for self‐assembled monolayers in near‐infrared organic photodetectors. The formation of zwitterions induces a strong electric field that significantly increases the work function of HTM‐coated indium tin oxide substrates. The devices exhibit low dark current and noise, along with high
