Narrowband terahertz radiation by an impulsive stimulated Raman scattering in an above-room-temperature organic ferroelectric benzimidazole
M. Sotome, N. Kida, S. Horiuchi +1
We observe a terahertz radiation from a hydrogen-bonded organic molecular ferroelectric 5,6-dichloro-2-methylbenzimidazole excited by a femtosecond laser pulse at room temperature.…
Spectral dynamics of topological shift-current in ferroelectric semiconductor SbSI
M. Sotome, M. Nakamura, J. Fujioka +8
Photoexcitation in solids brings about transitions of electrons/holes between different electronic bands. If the solid lacks an inversion symmetry, these electronic transitions sup…
Elliptically polarized terahertz radiation from a chiral oxide
R. Takeda, N. Kida, M. Sotome +1
Polarization control of terahertz wave is a challenging subject in terahertz science and technology. Here, we report a simple method to control polarization state of the terahertz…
Terahertz radiation imaging of ferroelectric domain topology in room-temperature organic supramolecular ferroelectrics
M. Sotome, N. Kida, S. Horiuchi +1
We demonstrate a new method to detect ferroelectric domains in inside and surface regions of organic ferroelectrics by mapping out two orthogonally polarized terahertz waves radiat…
Visualization of ferroelectric domains in boracite using emission of terahertz radiation
Y. Kinoshita, N. Kida, M. Sotome +5
We report on the emission of terahertz radiation by irradiation of femtosecond laser pulses in non-centrosymmetric paraelectric and ferroelectric phases of CoBOI bor…
Terahertz radiation by optical rectification in a hydrogen-bonded organic molecular ferroelectric crystal, 2-phenylmalondialdehyde
W. Guan, N. Kida, M. Sotome +5
Terahertz radiation by optical rectification has been observed at room temperature in a hydrogen-bonded organic molecular ferroelectric crystal, 2-phenyl malondialdehyde (PhMDA). T…
Terahertz radiation induced by coherent phonon generation via impulsive stimulated Raman scattering in paratellurite
M. Sotome, N. Kida, R. Takeda +1
We report on the observation of terahertz radiation in a non-centrosymmetric insulating oxide, paratellurite (-TeO) by irradiation of a femtosecond laser pulse at room tempe…
