Phonons and magnons are prospective information carriers to substitute the transfer of charge in nanoscale communication devices. Our ability to manipulate them at the nanoscale and with ultimate speed is examined by ultrafast acoustics and femtoseco... Read More about Ultrafast magnetoacoustics in Galfenol nanostructures.

Acoustic band engineering in terahertz quantum-cascade lasers and arbitrary superlattices (2023)
Journal Article
Demić, A., Valavanis, A., Dean, P., Li, L., Davies, A. G., Linfield, E. H., …Harrison, P. (2023). Acoustic band engineering in terahertz quantum-cascade lasers and arbitrary superlattices. Physical Review B, 107(23), Article 235411. https://doi.org/10.1103/physrevb.107.235411

We present theoretical methods for the analysis of acoustic phonon modes in superlattice structures, and terahertz-frequency quantum-cascade lasers (THz QCLs). Our generalized numerical solution of the acoustic-wave equation provides good agreement w... Read More about Acoustic band engineering in terahertz quantum-cascade lasers and arbitrary superlattices.
