Forcibly driven coherent soft phonons in GeTe with intense THz-rate pump fields
coherent soft phonons GeTe intense THz-rate pump fields
2010/11/23
We propose an experimental technique to generate large amplitude coherent phonons with irradiation of THz-rate pump pulses and to study the dynamics of phase transition in GeTe ferroelectrics.When a s...

Femtosecond dynamics of coherent optical phonons in GeTe/Sb2Te3 superlattices (SLs), a new
class of semiconductor SLs with three different states, have been investigated by using a reflectiontype pum...
