Nanogap structures for molecular nanoelectronics
This study is focused on the realization of nanodevices for nano and molecular electronics, based on molecular interactions in a metal-molecule-metal (M-M-M) structure. In an M-M-M system, the electronic function is a property of the structure and can be characterized through I/V measurements. The contact between the metals and the molecule was obtained by gold nanogaps (with a dimension of les...
متن کاملA solution state diode using semiconductor polymer nanorods with nanogap electrodes.
A solution state polymer diode, which uses regioregular poly(3-hexylthiophene-2,5-diyl) (P3HT):dichlorobenzene solution as the semiconductor between highly doped p-type silicon and aluminum electrodes has been built. Electrodes separated by a 40 nm gap enable intra-chain charge carrier transfer through the lengths of single polymer chains. This prevents chain to chain hopping and chain entangle...
متن کاملPlasmon resonance in individual nanogap electrodes studied using graphene nanoconstrictions as photodetectors.
We achieve direct electrical readout of the wavelength and polarization dependence of the plasmon resonance in individual gold nanogap antennas by positioning a graphene nanoconstriction within the gap as a localized photodetector. The polarization sensitivities can be as large as 99%, while the plasmon-induced photocurrent enhancement is 2-100. The plasmon peak frequency, polarization sensitiv...
متن کاملNonlinear electrical impedance spectroscopy of viruses using very high electric fields created by nanogap electrodes
Our living sphere is constantly exposed to a wide range of pathogenic viruses, which can be either known, or of novel origin. Currently, there is no methodology for continuously monitoring the environment for viruses in general, much less a methodology that allows the rapid and sensitive identification of a wide variety of viruses responsible for communicable diseases. Traditional approaches, b...
متن کاملFormation of Molecular-Scale Gold Nanogap Junctions via Controlled Electromigration
We have used a feedback method to control the electromigration of gold nanowires to form nanogap junctions, similar to recent reports [1, 2]. We have studied gold wires fabricated with conventional electron-beam and photolithography on thick SiO2 and thin Al2O3 (over Al) substrates. We find that the role of feedback mechanism is to control the local temperature of the electromigrating nanowire,...
