Ultrafast Umklapp-assisted electron-phonon cooling in magic-angle twisted bilayer graphene
Jake Dudley Mehew, Rafael Luque Merino, Hiroaki Ishizuka +8
Carrier relaxation measurements in moiré materials offer a unique probe of the microscopic interactions, in particular the ones that are not easily measured by transport. Umklapp s…
A pre-time-zero spatiotemporal microscopy technique for the ultrasensitive determination of the thermal diffusivity of thin films
Sebin Varghese, Jake Dudley Mehew, Alexander Block +8
Diffusion is one of the most ubiquitous transport phenomena in nature. Experimentally, it can be tracked by following point spreading in space and time. Here, we introduce a spatio…
Unraveling heat transport and dissipation in suspended MoSe crystals from bulk to monolayer
D. Saleta Reig, S. Varghese, R. Farris +14
Understanding thermal transport in layered transition metal dichalcogenide (TMD) crystals is crucial for a myriad of applications exploiting these materials. Despite significant ef…
Hot-Carrier Cooling in High-Quality Graphene is Intrinsically Limited by Optical Phonons
Eva A. A. Pogna, Xiaoyu Jia, Alessandro Principi +20
Many promising optoelectronic devices, such as broadband photodetectors, nonlinear frequency converters, and building blocks for data communication systems, exploit photoexcited ch…
Laser writable high-K dielectric for van der Waals nano-electronics
N. Peimyoo, M. D. Barnes, J. D. Mehew +9
Like silicon-based semiconductor devices, van der Waals heterostructures will require integration with high-K oxides. This is needed to achieve suitable voltage scaling, improved p…
Strain-engineering of twist-angle in graphene/hBN superlattice devices
Adolfo De Sanctis, Jake D. Mehew, Saad Alkhalifa +3
The observation of novel physical phenomena such as Hofstadter's butterfly, topological currents and unconventional superconductivity in graphene have been enabled by the replaceme…
