Largely Enhanced Output of the Non‐Contact Mode Triboelectric Nanogenerator via a Charge Excitation Based on a High Insulation Strategy

Advanced Energy Materials, 2022
The non‐contact triboelectric nanogenerator (TENG) based on floating plane motion can achieve a very low interface abrasion and high durability. However, the output performance of non‐contact TENG is still less than 72 µC m−2, due to the decay of tribo ...

A Plasmon-Enhanced SnSe2 Photodetector by Non-Contact Ag Nanoparticles.

Small, 2021
The 2D layered materials are promising candidates for broadband, low-cost photodetectors. One deficiency of 2D materials is the relatively low absorbance of light, limiting the applications of the 2D photodetectors. Doping of plasmonic nanoparticles into
