Journal ArticleDOI
Equivalent Circuits of a Self-Assembled Monolayer-Based Tunnel Junction Determined by Impedance Spectroscopy
TL;DR: In this article, the authors show that frequency-dependent AC measurements, impedance spectroscopy, make it possible to separate the contribution of each component from each other, e.g., the molecule-electrode contacts, protective layer (if present), or the SAM, to the electrical characteristics of the junctions.
Journal ArticleDOI
Correlation of morphology and charge transport in poly(3,4-ethylenedioxythiophene)-polystyrenesulfonic acid (PEDOT-PSS) films
TL;DR: In this article, a wide variation in the charge transport properties of poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT-PSS) films is attributed to the degree of phase segregation of the excess insulating polyanion.
Journal ArticleDOI
Reversible Soft Top‐Contacts to Yield Molecular Junctions with Precise and Reproducible Electrical Characteristics
TL;DR: In this article, a method to construct tunnel junctions based on self-assembled monolayers (SAMs) by forming reversible electrical contacts to SAMs using top-electrodes of a non-Newtonian liquid-metal (GaOx/EGaIn) stabilized in a microfluidic-based device is described.
Journal ArticleDOI

TL;DR: The plane-to-plane tunnelling conductivity of stacked CVD graphene layers can be improved significantly by inserting 1-pyrenebutyric acid N-hydroxysuccinimide ester between the graphene layers, which should be applicable to other types of stacked two-dimensional films.
Journal ArticleDOI
The Origin of the Odd-Even Effect in the Tunneling Rates across EGaIn Junctions with Self-Assembled Monolayers (SAMs) of n-Alkanethiolates.
TL;DR: The odd-even effects in SAM-based tunnel junctions of the form Ag(A-TS)-SC(n)//GaO(x)/EGaIn junctions are attributed to the properties of the SAMs and SAM-electrode interactions which both determine the shape of the tunneling barrier.
