Classification of Metal - Insulator Transitions: Relating characteristic Properties to Quantum Chemical Bonding Descriptors
Tim Bartsch, Carl-Friedrich Schön, Dasol Kim +3
Pressure induced metal insulator transitions (MIT) are classified by the evolution of characteristic optoelectronic and vibrational properties calculated with density functional th…
Bonding Signatures of Incipient Electron Localization in Topological Chiral Semimetals Near the Metal-Insulator Transition
Felix Hoff, Jonathan Frank, Mohit Raghuwanshi +11
How do electronic localization and delocalization compete in solids beyond the traditional limiting cases of metals and iono-covalent insulators? Topological chiral semimetals (TCS…
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, Nils von den Driesch, Alexander Pawlis +1
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 -r…
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…
Infrared Beam-shaping on Demand via Tailored Geometric Phase Metasurfaces employing the Plasmonic Phase-Change Material In3SbTe2
Lukas Conrads, Florian Bontke, Andreas Mathwieser +5
Conventional optical elements are bulky and limited to specific functionalities, contradicting the increasing demand of miniaturization and multi-functionalities. Optical metasurfa…
Atom probe tomography: a local probe for chemical bonds in solids
Oana Cojocaru-Mirédin, Yuan Yu, Jan Köttgen +5
Atom probe tomography is frequently employed to characterize the elemental distribution in solids with atomic resolution. Here we review and discuss the potential of this technique…
Direct programming of confined Surface Phonon Polariton Resonators using the plasmonic Phase-Change Material InSbTe
Lukas Conrads, Luis Schüler, Konstantin G. Wirth +2
Tailoring light-matter interaction is essential to realize nanophotonic components. It can be achieved with surface phonon polaritons (SPhPs), an excitation of photons coupled with…
Switching Casimir forces with Phase Change Materials
G. Torricelli, P. J. van Zwol, O. Shpak +4
We demonstrate here a controllable variation in the Casimir force. Changes in the force of up to 20% at separations of ~100 nm between Au and AgInSbTe (AIST) surfaces were achieved…
