应电信学部电子学院常超教授、李永东教授和IEEE NPSS Xi'an Chapter邀请，新加坡国立大学Cheng-Wei Qiu教授将作Metasurfaces and 2D materials相关学术报告。 Metasurfaces and 2D materials have been developing as two important candidates in the interfacial engineering, providing a plethora of new possibilities in novel optoelectronic functions and applications. The synergies between those two domains hold great promises in manipulating light-matter interaction. In this talk, I will start from reviewing and reporting some of the most recent developments in plasmonic and dielectric metasurfaces, and then focus on how monolayer TMDC and low-dimensional materials could be hybridized with classic metasurfaces to modulate and structure novel light behavior, such as zero-dark-current and bipolar semimetal photodetector, monolayer meta-lens of <1nm thickness, hybrid designs with enhanced SHG, PL, and tunable structural colors, by the coordinated hybridization between those two parties. Finally, we will elaborate our new breakthrough on van der Waals polaritonic metasurfaces, as a new roadmap toward ultra-low loss, long-range propagation, topological interfaces, and tailorable on-chip integrated functional devices. |
