| 摘 要： | 利用溶胶凝胶工艺在Pt/TiO2/SiO2/Si衬底上制备了Co掺杂量为0～10%(摩尔分数)的(Ba0.6Sr0.4) Ti1-xCoxO3薄膜.研究了薄膜的结构、表面形貌、介电性能与Co掺杂量的关系.薄膜的介电损耗随着Co含量的增加而减少,在摩尔含量10%时达到最小值0.0128.FOM值在摩尔含量为2.5%达到最大值20,它的介电常数、介电损耗和调谐量分别为639.42、0.0218、43.6%.

| Abstract: | (Ba_(0.6)Sr_(0.4))Ti_(1-x)Co_xO_3(BSTC) thin films doped Co from 0 to 10mol% were fabricated by sol-gel method on Pt/TiO_2/SiO_2/Si substrate.The structic,surface morphology and dielectric properties of BSTC thin films were investigated as a function of Co dopant concentration.The dielectric loss of the films decreased with increasing Co content.The loss factor of the 10mol% Co doped(Ba_(0.6)Sr_(0.4))Ti_(1-x)Co_xO_3 thin film showed the lowest value of 0.0128.The figure of merit(FOM) reached a maximum value of 20 at a 2.5mol% Co doped BSTC thin films.The dielectric constant,loss factor,and tunability of the 2.5mol% Co-doped(Ba_(0.6)Sr_(0.4))Ti_(1-x)Co_xO_3 thin films were 639.42,0.0218,and 43.6%,respectively. |
