Abstract

In this article, electron transport has been studied for a system consisting of a double-stranded DNA molecule with a telomeric sequence attached to two semi-finite electrodes of silicic nanoribbons. This study has been investigated using the tight-binding model and Green's function approach. By placing the DNA molecule in the middle of two silicon nanorod electrodes, we can see the electron passing channels in the system, and also the type of organic base connected to the electrodes showed a significant effect on the electron transport of the system. Calculations show that telomeric sequences such as TAGGGT, TTAGGG, and GTTAGG have the highest electrical conductivity compared to other sequences. We found that by controlling the gate voltage in the system, It is possible to control the current or load delivery. Also, by increasing the number of organic base pairs in the system, we saw an increase in current, and by controlling the number of organic base pairs, the transport characteristics can be controlled. This ability to control has many uses and a significant role in the manufacture of electronic components.
连接到硅电极的DNA测序中的电子传递:电子装置的设计
本文研究了由端粒序列连接到硅纳米带的两个半有限电极的双链DNA分子组成的系统的电子传递。本研究采用紧密结合模型和格林函数方法进行研究。通过将DNA分子置于两个硅纳米棒电极的中间,我们可以看到系统中的电子通过通道,并且连接到电极上的有机碱的类型对系统的电子传递也有显著的影响。计算表明,与其他序列相比,TAGGGT、TTAGGG和GTTAGG等端粒序列具有最高的电导率。我们发现,通过控制系统中的栅极电压,可以控制电流或负载的传递。同时,通过增加系统中有机碱基对的数量,我们看到电流的增加,通过控制有机碱基对的数量,可以控制传输特性。这种控制能力在电子元件的制造中有许多用途和重要作用。
