Outline of Final Research Achievements |
Atomic motions of a quartz oscillator under an alternating electric field are revealed by using a time-resolved synchrotron-radiation X-ray diffraction technique developed by this research subject. The lattice strain resonantly amplified by the alternating electric field is 10000 times larger than that induced by a static electric field. The resonantly amplified lattice vibration of the quartz oscillator is achieved by fast displacements of oxygen anions and collateral resilient deformation of Si-O-Si angles bridging rigid SiO4 tetrahedra.
