鍶鋇鈮SrXBa1-xNb2O6是近來很有潛力的電子陶瓷材料,其結構為正方鎢青銅,且為非中心對稱的鐵電材料。而關於鍶鋇鈮單晶在工業上的應用已相當廣泛,歸因於成長技術及性質已被詳細的研究,目前主要使用(Czoxhralski method),此技術擁有最高的線性光電係數、高的焦電係數以及良好的光折射效應。但由於單晶材料在實際應用上依然又到許多的限制,如形狀、大小、機械強度等,因此開發多晶鍶鋇鈮陶瓷是必然的趨勢。
本實驗將利用Cole Cole plot來深入探討SBN50在交流電場下其域壁動力學的機制,並分析在不同溫度與電場下的影響,對於電域壁移動的影響,再進一步探討機制中relaxation以及creep區段中各參數所代表的意義。
Strontium barium niobate ( SBN ) is a potential electronic ceramic material recently, which has Tetragonal Tungsten Bronze(TTB) structure.and is a non centro-symmerty ferroelectrics . Single SBN has been widely used in industry because of its growth technology and detailed study of its property. Now SBN uses CZ method to growth which has the highest linear electro-optical coefficient、pyroelectric coefficient and good photorefractive effect. Though the limit of single crystal property in practical use ,like shape , size, or hardness. Hence it is necessary to develop SBN ceramic.
Our experiment will use cole cole plot to study the domain wall dynamics of SBN50 under ac field, and analyze effect of temperature and electric field on domain wall dynamics. Finally , we will discuss the physical meaning of the parameter in creep and relaxation part.
