Abstract

The novel effect of direct current generation by carbon nanotubes with hot electron injection which may arise due to an electromagnetic radiation with commensurate frequencies has been theoretically investigated using the semiclassical Boltzmann kinetic equation with relaxation time assumed constant. The nonlinearity of the current voltage characteristics and the chiral effects have been considered. We note that the direct current is a result of the strong nonprabolicity of the energy of the carbon nanotubes for the case where it Bloch oscillates. It is shown that the novel expression for the direct current generation strongly and significantly dependence on the hot electron injection rate, which leads to strong oscillatory behavior and the shift of the regions of absolute negative conductivity from low to higher dimensionless amplitude β values with increasing injection rate. We predict that carbon nanotubes with hot electron injection may be useful for generation of direct current.

手性碳纳米管热电子注入精馏

摘要

使用半经典玻尔兹曼动力学方程，假设松弛时间为常数，理论上研究了碳纳米管通过热电子注入产生的直流电的新颖效应，这种效应可能是由于具有适当频率的电磁辐射引起的。已经考虑了电流电压特性的非线性和手性效应。我们注意到，直流电是碳纳米管在Bloch振荡的情况下强烈的非抛弃性的结果。结果表明，直流电产生的新表达式强烈且显着地依赖于热电子注入速率，这会导致强烈的振荡行为，并且随着注入速率的增加，绝对负电导率区域将从低到无量纲的振幅β值发生变化。我们预测通过热电子注入的碳纳米管可能对产生直流电有用。
