Journal Article
Greener, J. D., Akimov, A. V., Gusev, V., Kudrynskyi, Z., Beton, P. H., Kovalyuk, Z. D., Taniguchi, T., Watanabe, K., Kent, A., & Patanè, A. (2018). Coherent acoustic phonons in van der Waals nanolayers and heterostructures. Physical Review B, 98(7), Article 075408. https://doi.org/10.1103/PhysRevB.98.075408

Terahertz (THz) and sub-THz coherent acoustic phonons have been successfully used as probes of various quantum systems. Since their wavelength is in the nanometer range, they can probe nanostructures buried below a surface with nanometer resolution a...
