Research output: Contribution to journalArticlepeer-review


Coherent higher-order confined LO phonons are reported for the first time by a pump-probe technique in 70Ge/74Ge isotope superlattices. The Fourier-transformed spectra are well explained by a linear chain model and a bond polarizability approach.
