Lattice dynamics of LiNbTaO solid solutions: Theory and experiment
Felix Bernhardt, Soham Gharat, Alexander Kapp +8
Lithium niobate (LNO) and lithium tantalate (LTO) see widespread use in fundamental research and commercial technologies reaching from electronics over classical optics to integrat…
Hot electron dynamics in a semiconductor nanowire under intense THz excitation
Andrei Luferau, Maximilian Obst, Stephan Winnerl +8
We report THz-pump / mid-infrared probe near-field studies on Si-doped GaAs-InGaAs core-shell nanowires utilizing THz radiation from the free-electron laser FELBE. Upon THz excitat…
Unidirectional Ray Polaritons in Twisted Asymmetric Stacks
J. Álvarez-Cuervo, M. Obst, S. Dixit +25
The vast repository of van der Waals (vdW) materials supporting polaritons offers numerous possibilities to tailor electromagnetic waves at the nanoscale. The development of twisto…
