Influence of the Reference Electrode on the Performance of Single-Electrode Triboelectric Nanogenerators and the Optimization Strategies.

Owing to their unique advantages, single-electrode triboelectric nanogenerators (SETENGs) have gained wide attention and have been applied in myriad areas, especially in the burgeoning flexible/wearable electronics. However, there is still a lack of a clear understanding of SETENGs. For example, previous simulation models generally put the reference electrode perpendicularly below the working part, but in practice, the reference electrode is designed in various scenarios and noticeable differences in outputs often occur when the reference electrode changes.

Ultrafast Charge Transfer 2D MoS /Organic Heterojunction for Sensitive Photodetector.

The 2D MoS with superior optoelectronic properties such as high charge mobility and broadband photoresponse has attracted broad research interests in photodetectors (PD). However, due to the atomic thin layer of 2D MoS , its pure photodetectors usually suffer from inevitable drawbacks such as large dark current, and intrinsically slow response time. Herein, a new organic material BTP-4F with high mobility is successfully stacked with 2D MoS film to form an integrated 2D MoS /organic P-N heterojunction, facilitating efficient charge transfer as well as significantly suppressed dark current.
