讲座内容

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.
