Tellurium nanoparticles are used for broadband solar energy harvesting and efficient photothermal conversion.
High-resolution imaging is at the heart of revolutionary breakthroughs intelligent technologies, and it established as an important approach toward high-sensitivity information extraction/storage. However, due to incompatibility between non-silicon optoelectronic materials traditional integrated circuits well lack competent photosensitive semiconductors in infrared region, development ultrabroadband severely impeded.
