Ultrafast relaxation dynamics of the antiferrodistortive phase in Ca doped SrTiO3
M. Porer, M. Fechner, E. Bothschafter +19
The ultrafast dynamics of the octahedral rotation in Ca:SrTiO3 is studied by time resolved x-ray diffraction after photo excitation over the band gap. By monitoring the diffraction…

Ultrafast x-ray diffraction of a ferroelectric soft mode driven by broadband terahertz pulses
S. Grübel, J. A. Johnson, P. Beaud +14
Intense, few-cycle pulses in the terahertz frequency range have strong potential for schemes of control over vibrational modes in solid-state materials in the electronic ground-sta…
