Multifunctional BaTiO<sub>3</sub>-BiFeO<sub>3</sub> structures for coherent control of phononic states
ORAL
Abstract
The ability to control and manipulate coherent vibrational degrees of freedom, i.e. Coherent Phonons (CPs) on a nanoscale length and picosecond time scale promises to be crucial in the fields of quantum phononics. This talk will present new observations on BaTiO3-BiFeO3 films and nanorod arrays, which are materials systems with promise for a wide range of applications including phononics. We will present our observations that show this multifunctional material system could be suitable to enhance and control the generation and detection of CPs as well as to manipulate their amplitude, frequency, phase, and their subsequent interactions with carriers and spins.
