Direct Observation of Massless Excitons and Linear Exciton Dispersion
Luna Y. Liu, Steffi Y. Woo, Jinyuan Wu +3
Excitons -- elementary excitations formed by bound electron-hole pairs -- govern the optical properties and excited-state dynamics of materials. In two-dimensions (2D), excitons ar…
Nanosecond nanothermometry in an electron microscope
Florian Castioni, Yves Auad, Jean-Denis Blazit +8
Thermal transport in nanostructures plays a critical role in modern technologies. As devices shrink, techniques that can measure thermal properties at nanometer and nanosecond scal…
Nano-optics of transition metal dichalcogenides and their van der Waals heterostructures with electron spectroscopies
Steffi Y. Woo, Luiz H. G. Tizei
The outstanding properties of transition metal dichalcogenide (TMD) monolayers and their van der Waals (vdW) heterostructures, arising from their structure and the modified electro…
Quantum Confined Luminescence in Two dimensions
Saiphaneendra Bachu, Fatimah Habis, Benjamin Huet +13
Achieving localized light emission from monolayer two-dimensional (2D) transition metal dichalcogenides (TMDs) embedded in the matrix of another TMD has been theoretically proposed…
