The application of graphyne for a single-electron transistor (SET) that is operating in the Coulomb blockade regime is investigated in the first principles framework. Density functional theory modeling for graphyne has been used and the device environment has been described by a continuum model. The interaction between graphyne and the SET environment is treated with self-consistent Poisson equations. The charging energy as a function of gate voltage thus calculated has been used to obtain the charge stability diagram for the present system. The effect of electrode separation and the position of the molecule with respect to the dielectric on the gate coupling have been studied further. As compared with the previously studied systems on this line, graphyne has been observed to provide the gate coupling that is nearly close to that of benzene and graphene, but significantly greater than fullerene-based systems.

Oscillation Characteristics

In this paper, in order to analyze the performance of single-electron transistor (SET)-based analog-to-digital converter (ADC) circuits at room temperature, first, the quantum Coulomb blockade regime is explained and based on it we calculate and discuss the inherent Coulomb oscillation characteristics of room-temperature-operating SETs (or, in other words, ultra-small SETs). Then, to explain the performance of SET-based ADC structures, we explore the sensitivity of converter section of these structures to the inherent periodic oscillation characteristics. By simulating two different temperatures of 100[Formula: see text]K and 300[Formula: see text]K, we demonstrate that for proper performance of converter section of the SET-based ADCs, SETs must have inherent Coulomb oscillations with the same and high peak-to-valley current ratio (PVCR) and equal Coulomb peak spacing (i.e., equal [Formula: see text]. The Coulomb oscillation characteristics of the room-temperature-operating silicon SET show the Coulomb oscillations with unequal PVCRs and unequal Coulomb peak spacings (i.e., unequal [Formula: see text]. As a result, it can be seen that the room-temperature-operating SET-based ADCs never have a suitable output.

Experimental Values

The present paper discusses the investigation of electronic properties of anthracene-based single electron transistor (SET) operating in coulomb blockade region using Density Functional Theory (DFT) based Atomistix toolkit-Virtual nanolab. The charging energies of anthracene molecule in isolated as well as electrostatic SET environments have been calculated for analyzing the stability of the molecule for different charge states. Study also includes the analysis of SET conductance dependence on source/drain and gate potentials in reference to the charge stability diagram. Our computed charging energies for anthracene in isolated environment are in good agreement with the experimental values and the proposed anthracene SET shows good switching properties in comparison to other acene series SETs.
