Nanoelectromechanical systems based on multi-walled nanotubes: nanothermometer, nanorelay and nanoactuator
摘要：
我们报告了三种新型的基于碳纳米管的纳米机电系统：机电纳米温度计，纳米继电器和纳米管。纳米温度计可用于精确的温度测量在空间局部区域的尺寸为几百纳米。纳米继电器是一个记忆单元的原型，而纳米致动器可用于将向前的力转化为壁的相对旋转。这些纳米系统中的壁的相对运动由壁间相互作用能表面的形状限定。从头算和半经验计算已被用来估计这些纳米系统的操作特性和尺寸。
英文摘要：
We report on three new types of nanoelectromechanical systems based on carbon nanotubes: an electromechanical nanothermometer, a nanorelay and a nanomotor. The nanothermometer can be used for accurate temperature measurements in spatially localized regions with dimensions of several hundred nanometers. The nanorelay is a prototype of a memory cell, and the nanoactuator can be used for transformation of the forward force into the relative rotation of the walls. Relative motion of the walls in these nanosystems is defined by the shape of the interwall interaction energy surface. Ab initio and semi-empirical calculations have been used to estimate the operational characteristics and dimensions of these nanosystems.
