“…The quantum ballistic transport can be observed using this electrical doping phenomenon at the molecular level [ 85 ]. Using this theoretical approach electrically doped biomolecular switch is designed when using single-wall carbon nanotube (SWCNT) as electrodes [ 86 ]. NEGF formalisms help to design graphene-based anti-dot resonant tunnel diode [ 87 ].…”

Doping is the key feature in semiconductor device fabrication. Many strategies have been discovered for controlling doping in the area of semiconductor physics during the past few decades. Electrical doping is a promising strategy that is used for effective tuning of the charge populations, electronic properties, and transmission properties. This doping process reduces the risk of high temperature, contamination of foreign particles. Significant experimental and theoretical efforts are demonstrated to study the characteristics of electrical doping during the past few decades. In this article, we first briefly review the historical roadmap of electrical doping. Secondly, we will discuss electrical doping at the molecular level. Thus, we will review some experimental works at the molecular level along with we review a variety of research works that are performed based on electrical doping. Then we figure out importance of electrical doping and its importance. Furthermore, we describe the methods of electrical doping. Finally, we conclude with a brief comparative study between electrical and conventional doping methods.

Considering the importance of single-electron transistors (SETs), many studies have been done over the past decade to develop the use of SETs and improve their efficiency in both the experimental and theoretical fields. One of the most important challenges in SETs study is their optimization for use in humancompatible Nanobots for purposes such as drug delivery and destruction of cancer cells. Therefore, the use of human-compatible molecules as an island in these transistors is very significant. In this work, the density functional theory (DFT) & non-equilibrium Green's function (NEGF) methods have been used for SETs modeling study of the first principle computations in the coulomb barricade system of SETs based upon the metal-organic complex of ascorbic acid (vitamin C), thiamine (vitamin B1), riboflavin (vitamin B2), nicotinic acid (vitamin B3), pantothenic acid (vitamin B5), pyridoxine (vitamin B6), biotin (vitamin B7) and folic acid (vitamin B9). The isolated molecules and SET structures are analyzed based upon premises of overall energies, ionization energies, affection energies, addition energies, charging energies, gate coupling constant, density of states (DOS) plot, and charge stability diagrams (CSDs). It's established that riboflavin (vitamin B2) in the habitat of SET a decline in the additional energy and has the lowest addition energy and lowest charging energy at the neutral charge in the SET environment along with higher conductivity as evident from the CSD comparison has been revealed. Summing up the results and analyses indicate that a riboflavin molecule is a suitable option for SETs with a molecular island compatible with the human body.
