通过在KNbO 3中共掺杂Na（小离子尺寸）、Rb（大离子尺寸）或Cs（大离子尺寸），使用原始下拉方法生长碱金属（Na、Rb或Cs）掺杂的KNbO 3单晶。在室温下，用正交晶系方法成功地生长出了纯的和掺杂的KNbO_3单晶。它们的电性能，如介电常数和阻抗，被发现根据共掺杂元素的变化。
Alkali metal (Na, Rb or Cs) doped KNbO3single crystals are grown using an original pulling down method by means of co-doping with Na (small ionic size), Rb (large ionic sizes) or Cs (large ionic sizes) into KNbO3. Single-phase crystals are successfully grown with orthorhombic system at room temperature, for all the pure and doped KNbO3. Their electric properties, such as the dielectric constant and the impedance, are found to be changed according to the co-doping elements.
