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…
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,…
Generalized Electron Hydrodynamics, Vorticity Coupling, and Hall Viscosity in Crystals
Georgios Varnavides, Adam S. Jermyn, Polina Anikeeva +2
Theoretical and experimental studies have revealed that electrons in condensed matter can behave hydrodynamically, exhibiting fluid phenomena such as Stokes flow and vortices. Unli…
