“…NEGF is the most widely used method for studying the quantum transport in the GFMs. Yang et al studied the tunneling transport behavior of a zigzag graphyne NR tuned by gate and drain voltages, and proposed a tunneling FET based on it . Once the drain bias becomes larger than the band gap, the NR turns from the off-state to on-state, and the on/off ratio can reach 1 × 10 3 .…”

Further modulation on the tunneling current can be achieved by gate bias, and a larger gate bias leads to a larger current.…”

Graphyne and its family are new carbon allotropes in 2D form with both sp and sp hybridization. Recently, the graphyne with different structures have attracted great attentions from both experimental and theoretical communities, especially because the first successful synthesis of graphdiyne, which is a typical member of the graphyne family. In this review, recent theoretical progresses in the research of the graphyne family are summarized. More specifically, we systematically introduce the structural, mechanical, band, electronic transport, and thermal properties of graphyne and its family, as well as their possible applications, such as gas separation, water desalination and purification, anode material for ion battery, H storage, and catalysis application. Several related theoretical methods are also reviewed. The coexistence of sp and sp hybridization and the unique atom arrangement of the graphyne family members bring many novel properties and make them promising materials for many potential applications.

In this study, electrically doped bio-molecular p-in field-effect transistor (FET) is designed and its electronic properties are investigated. Density functional theory along with non-equilibrium Green's function based first principle approach is used to design the bio-molecular FET at sub-atomic region. Three Adenine and two Thymine molecules are attached together to form 6.24 nm long and 1.40 nm wide bio p-in FET. This device is attached with two platinum electrodes and wrapped with a metallic cylindrical gate at high vacuum. Intrinsic n and p regions can be made possible within a bio-molecular device at room temperature by electrical doping without explicit dopants, which leads to conduct current by the device both in forward and reverse bias. The various quantum mechanical properties have been calculated using Poisson's equations and self-consistent function for the bio-molecular FET. Among these various quantum mechanical properties, the authors obtain high quantum transmission along with satisfactory current for the proposed device during the room temperature operation. The goal of this study is to highlight the design of a bio-molecular p-in FET with satisfactory large current using ultra low power dissipation.
