Current oscillations in crystals of the wide-band dielectrics BaF2, CaF2, NaCl, and KBr
Mul'nikov V.S., Karetnikov A.A.
Current oscillations of frequencies ΙΟ '-ΙΟ4 Hz were observed in crystals of the wide-band dielectrics BaF2, CaF2, NaCl, and KBr in constant electric fields on the order of 106 V/m. The periods and the amplitudes of the current oscillations depend nonlinearly on the electric-field intensity.
