Nanosecond Nanothermometry in an Electron Microscope
Thermal transport in nanostructures plays a critical role in modern technologies. As devices shrink, techniques that can measure thermal properties at nanometer and nanosecond scales are increasingly needed to capture …
Quantum Confined Luminescence in Two Dimensions
The field of nanophotonics has witnessed a surge of interest in localized light emitters, driven by their potential to revolutionize optoelectronic devices. These emitters, including nanoparticles, nanowires, and quantum wells, …
Excitonic absorption signatures of twisted bilayer WSe2 by electron energy-loss spectroscopy
Moiré twist angle underpins the interlayer interaction of excitons in twisted van der Waals hetero- and homostructures. The influence of twist angle on the excitonic absorption of twisted bilayer tungsten …
Substrate influence on transition metal dichalcogenide monolayer exciton absorption linewidth broadening
The excitonic states of transition metal dichalcogenide (TMD) monolayers are heavily influenced by their external dielectric environment and depend on the substrate used. In this work, various wide band gap …
Nanoscale Modification of WS2 Trion Emission by Its Local Electromagnetic Environment
Structural, electronic, and chemical nanoscale modifications of transition metal dichalcogenide monolayers alter their optical properties. A key missing element for complete control is a direct spatial correlation of optical response …
