Uncovering the Three-Dimensional Structure of Upconverting Core-Shell Nanoparticles with Multislice Electron Ptychography
Stephanie M. Ribet, Georgios Varnavides, Cassio C. S. Pedroso +4
In photon upconverting core-shell nanoparticles, structure strongly dictates performance. Conventional imaging in scanning transmission electron microscopy has sufficient resolutio…
Probing carrier interactions using electron hydrodynamics
Georgios Varnavides, Adam S. Jermyn, Polina Anikeeva +1
Electron hydrodynamics arises when momentum-relaxing scattering processes are slow compared to momentum-conserving ones. While the microscopic details necessary to satisfy this con…
Generalized Design Principles for Hydrodynamic Electron Transport in Anisotropic Metals
Yaxian Wang, Georgios Varnavides, Polina Anikeeva +3
Interactions of charge carriers with lattice vibrations, or phonons, play a critical role in unconventional electronic transport of metals and semimetals. Recent observations of ph…
Finite-size effects of electron transport in PdCoO
Georgios Varnavides, Yaxian Wang, Philip J. W. Moll +2
A wide range of unconventional transport phenomena have recently been observed in single-crystal delafossite metals. Here, we present a theoretical framework to elucidate electron…
Capturing 3D atomic defects and phonon localization at the 2D heterostructure interface
Xuezeng Tian, Xingxu Yan, Georgios Varnavides +9
The 3D local atomic structures and crystal defects at the interfaces of heterostructures control their electronic, magnetic, optical, catalytic and topological quantum properties,…
Anisotropic phonon-mediated electronic transport in chiral Weyl semimetals
Christina A. C. Garcia, Dennis M. Nenno, Georgios Varnavides +1
Discovery and observations of exotic, quantized optical and electrical responses have sparked renewed interest in nonmagnetic chiral crystals. Within this class of materials, six g…
