Determining the complex second-order optical susceptibility in macroscale van der Waals heterobilayers
Zeyuan Zhu, Taejun Yoo, Kanchan Shaikh +5
We report on the experimental characterization of the second-order susceptibility in MoSe/WS heterobilayers, including their hidden complex phases. To this end, we develope…
