Challenges and Opportunities of Upconversion Nanoparticles for Emerging NIR Optoelectronic Devices

open access: yesAdvanced Materials, EarlyView.
The special photo‐responsiveness of upconversion nanoparticles has opened up a new path for the advancement of near‐infrared (NIR)‐responsive optoelectronics. However, challenges such as low energy‐conversion efficiency and high nonradiative losses still persist.

Electrochemical Anodization for the Fabrication of Wafer‐Scale p‐Type Organic Permeable Base Transistors Arrays with MHz Operation

open access: yesAdvanced Materials, EarlyView.
This work presents a wafer‐scale fabrication method for high‐performance p‐type organic permeable base transistors (OPBTs) using electrochemical anodization. The anodized OPBTs achieve high on‐current density, low leakage, MHz‐range operation, and exceptional current gain.

Mechanical Resonant Sensing of Spin Texture Dynamics in a 2D Antiferromagnet

open access: yesAdvanced Materials, EarlyView.
Detection of antiferromagnetic spin texture in a 2D magnetic crystal is achieved through nanomechanical resonators at radio frequencies. Sharp magnetic transitions that lead to abrupt changes in mechanical linear and nonlinear responses are assigned to antiferromagnetic domain motions.

Over Tenfold Increase in Current Amplification Due to Anisotropic Polymer Chain Alignment in Organic Electrochemical Transistors

open access: yesAdvanced Materials, EarlyView.
How to boost the IDS output of an OECT? Anisotropic polymer alignment along the channel direction enables a 13‐fold increase in IDS. Such channel engineering opens the door to unprecedented signal amplification (here gmL/Wd = 2 580 S cm−1 with a PBTTT‐backbone bearing single‐ether side chains), faster ON/OFF switching, and improved stability for the ...
