Growth and decay processes of linear domains in lithium niobate single crystals fabricated utilizing scanning probe microscopy were investigated. It is found that the initial configuration of linear domains is dependent on the fabrication parameters as scan velocity and voltage. The linear domains decay at the part where the domain width is small for two different processes. A comparison of critical stable domain size between dot and linear domains was carried out. The critical linear domain width is 0.7 times as large as the critical diameter of dot domain at the same sample thickness due to their smaller surface energy. [ABSTRACT FROM AUTHOR]
