Softening Mechanism of Coherent Phonons in Antimony Under High Density Photoexcitation
H. Kumagai, I. Matsubara, J. Nakahara +1
We have investigated the dynamical properties of coherent phonons generated in antimony under high density photo excitation. Precise measurements and extended analysis of coherent…
