Thermoelectric Properties of BiTe

Journal of Physics: Conference Series, 2020
Abstract Research on crystal structures and thermoelectric properties has been carried out using BiTe material. The sintering method used is hot press. Hot press pressure comes from the bottom up. Temperature variations used in hot press are 400, 450, and 500°C. Analysis of crystal structure used XRD. Based on the XRD results, the result

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

Advanced 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.
