Prof. Tao Wang, Full Professor of the Institute of Functional Nano & Soft Materials of Soochow University, delivered an engaging talk on the “Electrically-driven nano-light sources based on tunnel junctions” on 11 December 2024. Prof. Wang shared his extensive research on Utilizing plasma circuits, with the ability to guide photons in sub-difiractional dimensions, as an alternative to photonic circuits, especially at the micro- or nano-scale.
With a prolific publication record, Prof. Wang has authored peer-reviewed journal papers, So far, he has published 40 papers as the first or corresponding author, including Nature Photonics (2), Nature Communications (1),Nao Letters (4),Advanced Materials (1), Advanced Science(l), Small (3)etc., and has been granted 5 patents. In May 2019, he joined the Institute of Functional Nano and Soft Materials of Soochow University.
In his presentation, Prof. Wang provided a comprehensive overview of the basic physical properties of plasmon on electrically excited surfaces of tunneling junctions (scanning tunneling microscope tunneling junctions, metal-oxide-metal tunneling junctions, monolayer tunneling junctions). These results show the potential of tunnel junction as a miniaturized light source with low energy consumption, which can be integrated with controllable electric drive, and provide light source conditions for the further development of miniaturized integration of nano optical chips.
