Recently, a research group helmed by Professor Sun Dong from the Center for Quantum Materials Science at Peking University's School of Physics, working in tandem with Professor Pan Anlian's team from the School of Materials Science and Engineering at Hunan University, and Professor Zeng Changgan from the Department of Physics at the University of Science and Technology of China, has achieved a notable milestone in the realm of two-dimensional (2D) tellurium (Te) nanosheets. They have successfully realized highly efficient, electrically adjustable mid-infrared photoluminescence (PL). Through the construction of a dual-gate field-effect transistor device, the research team has not only attained significant electrical modulation of PL intensity but also maintained exceptionally high wavelength stability. The pertinent research results have been published in a relevant academic journal.
