Structural Studies Of Materials Using Time-Resolved X-ray Diffraction
Författare
Summary, in English
The ferroelastic switching between different structures in the ferroelectric phase of potassium dihydrogen phosphate (KDP) was observed via time-resolved X-ray diffraction. This material undergoes a phase transition from the paraelectric phase above the Curie Temperature (Tc) to the ferroelectric phase below Tc.
An alternative method of initiating ultrafast structural changes in a ferroelectric material was studied at the Stanford Linear Accelerator Centre, where THz radiation was used as a pump, and femtosecond laser pulses as the probe, in order to study the nonlinear response of ferroelectric material to THz radiation.
