Coupling-Enhanced Broadband Mid-Infrared Light Absorption in Graphene Plasmonic Nanostructures
Bingchen Deng, Qiushi Guo, Cheng Li +6
Plasmons in graphene nanostructures show great promise for mid-infrared applications ranging from a few to tens of microns. However, mid-infrared plasmonic resonances in graphene n…
Determining the vibrations between sensor and sample in SQUID microscopy
Daniel Schiessl, John R. Kirtley, Lisa Paulius +8
Vibrations can cause noise in scanning probe microscopies. Relative vibrations between the scanning sensor and the sample are important but can be more difficult to determine than…
Polaritons in layered 2D materials
Tony Low, Andrey Chaves, Joshua D. Caldwell +7
In recent years, enhanced light-matter interactions through a plethora of dipole-type polaritonic excitations have been observed in two-dimensional (2D) layered materials. In graph…
Quantum decoherence dynamics of divacancy spins in silicon carbide
Hosung Seo, Abram L. Falk, Paul V. Klimov +3
Long coherence times are key to the performance of quantum bits (qubits). Here, we experimentally and theoretically show that the Hahn-echo coherence time (T2) of electron spins as…
High fidelity bi-directional nuclear qubit initialization in SiC
Viktor Ivády, Paul V. Klimov, Kevin C. Miao +6
Dynamic nuclear polarization (DNP) is an attractive method for initializing nuclear spins that are strongly coupled to optically active electron spins because it functions at room…
Electron optics with ballistic graphene junctions
Shaowen Chen, Zheng Han, Mirza M. Elahi +9
Electrons transmitted across a ballistic semiconductor junction undergo refraction, analogous to light rays across an optical boundary. A pn junction theoretically provides the equ…
