Dynamics of coherent optical phonons in a Bi2Se3 crystal

Published: Jan 1, 2012
Abstract
Coherent A1g1, A1g2, and Eg2 phonons in Bi2Se3 are observed using ultrafast spectroscopy. Their initial phases suggest different coupling strengths with photo-excited electrons. Their decay rates per oscillations are almost the...
