摘要(Abstract):
以过渡金属硫化物、氮化硼等二维层状材料为基础,研究了一种简单可靠的集成电路制造方法。在这项工作中,采用射频磁控溅射在室温下逐层制备了M/BN/MoS_2(M=Al、Ti、Mo和Ag)纳米薄膜,其中BN/MoS_2为未发生化学反应的异质结构,然后在500℃进行退火。结果表明:所制备的金属(Al、 Ti、 Mo和Ag)、BN和MoS_2薄膜均匀连续,特别是BN/MoS_2异质结构界面清晰、结合紧密。退火后,顶层MoS_2薄膜颗粒大小、粗糙度和结晶性显著提高,且杂质减少甚至消失,其中Ag/BN膜基底上MoS_2薄膜结晶性最好,且出现了较大的片层状形态。电性能测试显示金属/BN和BN/MoS_2异质结构界面的肖特基势垒使得样品的I-V特性曲线呈明显的非线性。Ti基由于退火后氧化,电阻率最大,Mo基功函数最大,电阻率其次,Ag基功函数相对较低所以电阻率较低,而Al则由于低的功函数、结构匹配及载流子浓度等因素导致其电阻率最低。
