Ultrafast terahertz-field-driven ionic response in ferroelectric BaTiO
F. Chen, Y. Zhu, S. Liu +31
The dynamical processes associated with electric field manipulation of the polarization in a ferroelectric remain largely unknown but fundamentally determine the speed and function…
Picosecond electric-field-induced threshold switching in phase-change materials
Peter Zalden, Michael J. Shu, Frank Chen +16
Many chalcogenide glasses undergo a breakdown in electronic resistance above a critical field strength. Known as threshold switching, this mechanism enables field-induced crystalli…
Ultrafast THz Field Control of Electronic and Structural Interactions in Vanadium Dioxide
A. X. Gray, M. C. Hoffmann, J. Jeong +34
Vanadium dioxide, an archetypal correlated-electron material, undergoes an insulator-metal transition near room temperature that exhibits electron-correlation-driven and structural…
Nano-optical imaging of WSe2 waveguide modes revealing light-exciton interactions
Z. Fei, M. E. Scott, D. J. Gosztola +12
We report on nano-optical imaging study of WSe2 thin flakes with the scanning near-field optical microscopy (NSOM). The NSOM technique allows us to visualize in real space various…
