Opto-Electronic Devices Based on Refractory and 2D Materials

In this article, we highlight our current work on optoelectronic devices based on 2D and refractory materials. We initially present our past work on nano-antennas based upon refractory materials and show how they can handle higher fluences than noble metals. We then show how refractory ceramics can be applied to ultraviolet and visible photodetectors based on refractory carbides/borides, with potential integration to silicon carbide power electronic devices. Finally, we exploit 2D dichalcogenides and show how to achieve perfect absorbance and efficient strong coupling in the materials, when combined with nanostructures such as nano-cylinders and meta-gratings.
