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…
THz-driven ultrafast spin-lattice scattering in amorphous metallic ferromagnets
S. Bonetti, M. C. Hoffmann, M. -J. Sher +5
We use single-cycle THz fields and the femtosecond magneto-optical Kerr effect to respectively excite and probe the magnetization dynamics in two thin-film ferromagnets with differ…
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…
Transient terahertz photoconductivity measurements of minority-carrier lifetime in tin sulfide thin films: Advanced metrology for an early-stage photovoltaic material
R. Jaramillo, Meng-Ju Sher, Benjamin K. Ofori-Okai +7
Materials research with a focus on enhancing the minority-carrier lifetime of the light-absorbing semiconductor is key to advancing solar energy technology for both early-stage and…
Insulator-to-metal transition in sulfur-doped silicon
Mark T. Winkler, Daniel Recht, Meng-Ju Sher +3
We observe an insulator-to-metal (I-M) transition in crystalline silicon doped with sulfur to non- equilibrium concentrations using ion implantation followed by pulsed laser meltin…
