Excimer Formation in Zinc-phthalocyanine Revealed using Ultrafast Electron Diffraction
Sebastian Hammer, Tristan L. Britt, Laurenz Kremeyer +4
The formation of excited dimer states, so called excimers, is an important phenomenon in many organic molecular semiconductors. In contrast to Frenkel exciton-polaron excited state…
A momentum-resolved view of polaron formation in materials
Tristan L Britt, Fabio Caruso, Bradley J Siwick
A combined experimental and computational methodology for interrogating the phonon contribution to polaron formation in real materials is developed. Using LiF as an example, we sho…
Ultrafast Electron Diffuse Scattering as a Tool for Studying Phonon Transport: Phonon Hydrodynamics and Second Sound Oscillations
Laurenz Kremeyer, Tristan L. Britt, Bradley J. Siwick +1
Hydrodynamic phonon transport phenomena, like second sound, have been observed in liquid Helium more than 50 years ago. More recently second sound has been observed in graphite at…
Ultrafast Phonon-Diffuse Scattering as a Tool for Observing Chiral Phonons in Monolayer Hexagonal Lattices
Tristan L Britt, Bradley J. Siwick
At the 2D limit, hexagonal systems such as monolayer transition metal dichalcogenides (TMDs) and graphene exhibit unique coupled spin and momentum-valley physics (valley pseudospin…
Direct view of phonon dynamics in atomically thin MoS
Tristan L. Britt, Qiuyang Li, Laurent P. René de Cotret +7
Transition metal dichalcogenide monolayers and heterostructures are highly tunable material systems that provide excellent models for physical phenomena at the two-dimensional (2D)…
Extreme Lightwave Electron Field Emission from a Nanotip
Dominique Matte, Nima Chamanara, Lauren Gingras +4
We report on sub-cycle terahertz light-field emission of electrons from tungsten nanotips under extreme conditions corresponding to a Keldysh parameter . Local p…
