Abstract :
Scanning nonlinear dielectric microscopy (SNDM) is the first successful purely electrical method for observing ferroelectric domains. Its resolution has now reached the sub-nanometer order. In this paper, a fundamental study on application of the SNDM system to a ferroelectric reading and writing system is performed. First, to check the performance of the SNDM system as a ferroelectric recording system, we conduct a fundamental study on the writing of a domain inversion dot in a PZT thin film and succeed in achieving very small domain dots with a size of 25 nm. Next, we form small inverted domain dots in stoichiometric LiTaO3 single crystals for the purpose of a basic investigation of domain dynamics in a very small area. The relationship between the voltage for domain reversal and the inverted area and the relationship between the inverted domain area and the voltage application time are obtained
