Nonresonant optomechanical control of structural phases
Jiaojian Shi, Yijing Huang, Christian Heide +24
Optical tweezers demonstrate how light can exert forces to trap, repel, and manipulate microscopic particles without absorption. Recent theory has suggested that such forces can ex…
Understanding and Designing Phase Change Materials: Insights from Atom Probe Tomography
Jan Köttgen, Jan Köttgen, Nils von den Driesch +2
Phase Change Materials (PCMs) can be rapidly and reversibly switched between their amorphous and crystalline state; a transition which is accompanied by a pronounced change of opto…
Divergent Coherent Phonon Responses Across the Metal-Insulator Crossover
Felix Hoff, Timo Veslin, Tim Bartsch +3
Ultrafast laser control of material properties hinges on understanding light-matter interactions. We use two experimentally accessible response functions, laser fluence induced pho…
Robust Material Properties in Epitaxial InTe Thin Films Across Varying Thicknesses
Maximilian Buchta, Felix Hoff, Lucas Bothe +8
Sesqui-chalcogenides serve as a critical bridge between traditional semiconductors and quantum materials, offering significant potential in applications such as thermoelectrics, ph…
Isothermal Annealing Effects on -Relaxations and Crystallization Behaviors in Amorphous GeTe
Arune Makareviciute, Qun Yang, Tomoki Fujita +12
A secondary -relaxation process is often the dominant source of atomic dynamics below in many glass forming systems. Recent studies reported the presence of …
Tailoring hBN's Phonon Polaritons with the Plasmonic Phase-Change Material In3SbTe2
Lina Jäckering, Aaron Moos, Lukas Conrads +8
Polaritons in van-der-Waals materials (vdWM) promise high confinement and multiple tailoring options by optical structures, e.g., resonators, launching structures and lenses. These…
