Photo-ferroelectric noise effect. Observation and investigation
Luk'yanchikova N.B., Sheinkman M.K., Lityuchii A.P.
A new photo-ferroelectric effect has been observed, and was named by us photo-ferroelectric noise. Its gist is that when Á Ó-domain ÷Áôà3 single crystal is illuminated, there appears on electrodes deposited on the (001) face a fluctuating voltage in a wide frequency range, greatly exceeding the thermal-noise level. Some singularities of the phenomenon are investigated and its possible mechanisms are considered.
