TMTSF单晶晶体管中的类带输运和陷阱

Band-like transport and trapping in TMTSF Single Crystal Transistors

H. Xie, H. Alves, A. F. Morpurgo

摘要:

我们进行了四甲基四硒富瓦烯(TMTSF)单晶场效应晶体管,其电气特性表现出明确的签名的材料的固有传输特性的实验和理论研究。我们引入了一个简单的,定义明确的模型的基础上的物理参数,我们成功地再现定量的设备性能作为温度和载流子密度的函数。该分析允许其内部的一致性进行检查,并能够可靠地提取材料中的浅陷阱和深陷阱的密度和特征能量。我们的研究结果表明,浅陷阱起源于深陷阱中固定的电荷产生的静电势波动。

英文摘要:

We perform a combined experimental and theoretical study of tetramethyltetraselenafulvalene (TMTSF) single-crystal field-effect transistors, whose electrical characteristics exhibit clear signatures of the intrinsic transport properties of the material. We introduce a simple, well-defined model based on physical parameters and we successfully reproduce quantitatively the device properties as a function of temperature and carrier density. The analysis allows its internal consistency to be checked, and enables the reliable extraction of the density and characteristic energy of shallow and deep traps in the material. Our findings indicate that shallow traps originate from electrostatic potential fluctuations generated by charges fixed in the deep traps.
