Near-unity light absorption in a monolayer WS2 van der Waals heterostructure cavity
Itai Epstein, Bernat Terrés, André J. Chaves +12
Excitons in monolayer transition-metal-dichalcogenides (TMDs) dominate their optical response and exhibit strong light-matter interactions with lifetime-limited emission. While var…
Measuring valley polarization in two-dimensional materials with second-harmonic spectroscopy
Yi Wei Ho, Henrique Guimarães Rosa, Ivan Verzhbitskiy +6
A population imbalance at different valleys of an electronic system lowers its effective rotational symmetry. We introduce a technique to measure such imbalance - a valley polariza…
Wide-field spectral super-resolution mapping of optically active defects in hBN
Jean Comtet, Evgenii Glushkov, Vytautas Navikas +6
Point defects can have significant impacts on the mechanical, electronic and optical properties of materials. The development of robust, multidimensional, high-throughput and large…
