A compact model for molecular electronic devices that considers the accumulation of charge on the molecule by an equivalent capacitive charging process which is suitable for transient analyses is presented. The model is used to examine the viability of molecular devices in future electronics applications. Further Monte Carlo simulations are carried out to examine digital behaviour in the face of a statistical spread in device characterising parameters, revealing relatively robust circuit behaviour and showcasing the model's capability to relate fundamental physical constants governing the quantum mechanical behavior of the device to abstract figures of merit.
Abstract-We have used the Breit-Wigner resonance formula to model a class of molecular electronics devices with the aim to establish an abstract model for a molecular electronic device that can be used in a general cross bar architecture of future nanoelectronic systems. We show that the molecular I-V curves can be characterized by a very small number of variables including the couplings between the contact and leads.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
