| 摘 要： | 用离子束增强沉积方法制备掺杂Ar和W的VO2多晶薄膜,明显改变了VO2薄膜的相变温度.试验发现,薄膜存在一个形成VO2结构的临界结晶温度,该温度随薄膜制备时沉积条件的不同而改变.选择适当的杂质和退火条件可以将VO2薄膜的相变温度降低到室温附近,获得较高室温电阻-温度系数的薄膜.

| Abstract: | Polycrystalline VO_2 films doped with argon and tungsten are prepared with modified Ion Beam Enhanced Deposition(IBED) method.The experimental results indicated that the phase transition temperature(Tc) of the doped IBED VO_2 films is changed evidently,which is related to undoping VO_2 films,and there exists a critical temperature for crystallization of VO_2,which changes with the different deposition conditions of the IBED method.The temperature of the vanadium dioxide film could be reduced to room temperature effectively by selecting the proper impurity element and the annealing conditions.It is possible to increase the temperature coefficient of resistance(C_T,R) of the films for IR application. |
