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 Co${}_3$B${}_7$O${}_{13}$I bor…
