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.

Van der Waals Integration of 1D Nb2Pd3Se8 and 2D WSe2 for Gate‐Tunable In‐Sensor Image Processing

open access: yesAdvanced Materials, EarlyView.
We developed self‐powered photodetectors for in‐sensor image processing by integrating high‐quality 1D Nb2Pd3Se8 with 2D WSe2. The type‐I junction and a 1D van der Waals interfaceenable gate‐tunable switching between n‐p and n‐n+ configurations, yieldingbroadband bi‐directional photoresponse.

All‐Heat Control of Magnetization Dynamics on Van der Waals Magnets

open access: yesAdvanced Materials, EarlyView.
Heat dissipation in nanomagnetic devices mediated by femtosecond laser excitation constitutes one of the pressing challenges toward energy‐efficient information communication technologies. Here it is shown that heat and magnetization play together to determine the ultrafast spin dynamics of van der Waals magnets across any substrates and magnet ...
