|Title:||Robust reproducible large-area molecular rectifier junctions||Authors:||Che, H.-J.
|Issue Date:||2008||Citation:||Che, H.-J., Chia, P.-J., Chua, L.-L., Sivaramakrishnan, S., Tang, J.-C., Wee, A.T.S., Chan, H.S.O., Ho, P.K.H. (2008).

ScholarBank@NUS Repository. https://doi.org/10.1063/1.2940592||Abstract:||Stable rectifying molecular junctions have been obtained by sandwiching self-assembled monolayer films containing "push-pull" donor- π -acceptor (D-π -A) moieties between Au and poly(3,4-ethylenedioxythiophene) electrodes. These D-π -A moieties possess moderate molecular dipoles, but assemble into films with nearly zero dipole moment due to adoption of high average tilt angles. Nevertheless reproducible and well-behaved rectifications (ratio up to 3.3) in the expected polarity were obtained. At low biases, the current-voltage characteristics follow Simmon's tunneling theory with reasonable barrier heights and an effective tunnel mass of ∼0.5 me. This suggests that asymmetric tunneling, and not carrier injection, is the origin of the rectification. © 2008 American Institute of Physics.||Source Title:||Applied Physics Letters||URI:||http://scholarbank.nus.edu.sg/handle/10635/53139||ISSN:||00036951||DOI:||10.1063/1.2940592|
