【摘要】 当用直拉法生长掺杂的LiNbO₃单晶体时,使一脉冲电流通过固液界面,观察到晶体中铁电畴组态的变化.测定了调制电流与正、负交替铁电畴组态的一一对应关系.用这种新方法,可以制备大面积的、具有一维周期层状铁电畴结构的LiNbO₃晶体.更多还原

【Abstract】 The alternation of ferroelectric domain structure has been observed in doped LiNbO3 crystals when the rectangular electric current pulses are applied across the solid-liquid interface during crystal growth by Ozochralski-method. The correspondence relation between ferroelectric domains and modulated current has been demonstrated. Using this new method, LiNbO3 with one dimensional periodic laminar domain structures have been prepared.更多还原
