Emerging 2D electronic materials have shown great potential for regulating and controlling optoelectronic processes. A 2D ferroelectric semiconductor coupled with the piezo-phototronic effect may bring unprecedented functional characteristics. Here, …

Enhanced performances of Si/CdS heterojunction near-infrared photodetector by the piezo-phototronic effect

Owing to the compatibility with the traditional integrated circuit technology, it is of great significance to enhance the photoresponse performance of Silicon (Si)-based photodetectors (PDs) in the near-infrared (NIR) wavelength. Here, by introducing …

Largely Improved Near-Infrared Silicon-Photosensing by the Piezo-Phototronic Effect

Although silicon (Si) devices are the backbone of modern (opto-)electronics, infrared Si-photosensing suffers from low-efficiency due to its limitation in light-absorption. Here, we demonstrate a large improvement in the performance, equivalent to a …

Simultaneously Enhancing Light Emission and Suppressing Efficiency Droop in GaN Microwire-Based Ultraviolet Light-Emitting Diode by the Piezo-Phototronic Effect

Achievement of p-n homojuncted GaN enables the birth of III-nitride light emitters. Owing to the wurtzite-structure of GaN, piezoelectric polarization charges present at the interface can effectively control/tune the optoelectric behaviors of local …
