Self‐Powered Diamond Homojunction Photodetectors for Stable Ultraviolet Sensing Under High Temperatures

Electron, EarlyView.
In this work, we report an unintentionally doped/boron‐doped diamond homojunction ultraviolet photodetector grown by microwave plasma chemical vapor deposition. The device achieves self‐powered ultraviolet detection with negligible performance degradation even at temperatures of up to 250°C.

Light‐Modulated Exchange Bias in Multiferroic Heterostructures

Electron, EarlyView.
In this article, exchange bias and magnetization are modulated with visible light at room temperature in PMN‐PZT/FeGa/IrMn multiferroic heterostructures. Photostrictive effect is the main mechanism leading to the modulation of magnetic anisotropy and interfacial exchange bias coupling between the ferromagnetic and antiferromagnetic layers.
