Precise one-dimensional nanochannels in transition metal dichalcogenides as building blocks for advanced nanophotonics
Abhay V. Agrawal, Wouter Holman, Betül Küçüköz +2
Atomically sharp edges are essential for future high-index nanophotonic structures, yet conventional lithography and dry etching methods inevitably introduce edge roughness that li…
Humidity-enhanced NO gas sensing using atomically sharp edges in multilayer MoS
Abhay V. Agrawal, Alexander Yu. Polyakov, Jens Eriksson +2
Ambient humidity poses a significant challenge in the development of practical room temperature NO gas sensors. Here, we employ atomically precise zigzag edges in multilayer Mo…
Ultrathin 3R-MoS metasurfaces with atomically precise edges for efficient nonlinear nanophotonics
George Zograf, Betül Küçüköz, Alexander Yu. Polyakov +5
Dielectric metasurfaces that combine high-index materials with optical nonlinearities are widely recognized for their potential in various quantum and classical nanophotonic applic…
Defect-assisted reversible phase transition in mono- and few-layer ReS
George Zograf, Andrew B. Yankovich, Betül Küçüköz +9
Transition metal dichalcogenide (TMD) materials have attracted substantial interest due to their remarkable excitonic, optical, electrical, and mechanical properties, which are hig…
Quantum trapping and rotational self-alignment in triangular Casimir microcavities
Betül Küçüköz, Oleg V. Kotov, Adriana Canales +4
Casimir torque -- a rotational motion caused by the minimization of the zero-point energy -- is a problem that attracts significant theoretical and experimental interest. Recently,…
