Electron Ptychography Reveals Correlated Lattice Vibrations at Atomic Resolution
Anton Gladyshev, Benedikt Haas, Thomas C. Pekin +4
In this paper we introduce an electron ptychography reconstruction framework, CAVIAR -- Correlated Atomic Vibration Imaging with sub-Angstrom Resolution -- that reveals an entirely…

Ultrafast phonon-mediated dephasing of color centers in hexagonal boron nitride probed by electron beams
Masoud Taleb, Paul Bittorf, Mximilian Black +7
Defect centers in hexagonal boron nitride have been extensively studied as room temperature single photon sources. The electronic structure of these defects exhibits strong couplin…
