— 2 min read

A team of researchers from Fudan University has made a significant discovery in the field of nanotechnology, developing 3D nanomembranes with unique optical and optoelectronic properties. These nanomembranes, which are freestanding thin films, exhibit enhanced light absorption and broad-angle detection, enabling a wide range of applications, including passive and active devices such as sensors, metamaterial fibers, phototransistors, and bolometers. The research, funded by the Science & Technology Commission of Shanghai Municipality (STCSM), has been published in Advanced Functional Materials.

The researchers, led by Yang Wang, have successfully developed a method to evaluate and manage the thermal effects in these 3D nanomembranes, which is crucial for their performance in various applications. The study shows that thermal accumulation occurs in these nanomembranes under laser illumination, compromising device performance. However, by optimizing laser parameters and ambient conditions, the researchers were able to achieve precise thermal control, preventing thermal damage and enhancing response in devices such as Si microtube resonators and VO2-based bolometers.

This breakthrough has far-reaching implications for the development of advanced optoelectronic and photonic devices, enabling rational design and thermal management of 3D microdevices. The researchers believe that this work provides a promising strategy for the thermal design of 3D microdevices in photonics and optoelectronics.
