Preparation of Cd-doped BZCN thin film and its dielectric properties
【摘要】 用射频磁控溅射法,在Pt/Si基片上制备了立方烧绿石结构的Cd掺杂Bi1.5Zn0.7Cd0.3Nb1.5O7(BZCN)薄膜。研究了衬底温度对薄膜结构、表面形貌以及介电性能的影响。结果表明,沉积温度为600℃,退火温度为700℃制备的薄膜,在测试频率为100 kHz,测试电场强度为1.33×106 V/cm的条件下,介电可调率达到11.8%,tanδ小于0.004 2。
【Abstract】 The Bi1.5Zn0.7Cd0.3Nb1.5O7(BZCN) thin films of cubic pyrochlore phase were prepared on Pt/Si substrate using RF magnetron sputtering method.Investigated were the effects of substrate temperature on the structures and surface morphology,dielectric properties of films.The BZCN thin films sputtered with a deposited temperature of 600 ℃ and annealed temperature at 700 ℃ showed a dielectric tunability of 11.8 %,tan δ lower than 0.0042 at E of 1.33×106 V/cm and measurement frequency of 100 kHz.
