Download or read book Energy Level Alignment and Electron Transport Through Metal Organic Contacts written by Enrique Abad and published by Springer Science & Business Media. This book was released on 2012-09-16 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, ever more electronic devices have started to exploit the advantages of organic semiconductors. The work reported in this thesis focuses on analyzing theoretically the energy level alignment of different metal/organic interfaces, necessary to tailor devices with good performance. Traditional methods based on density functional theory (DFT), are not appropriate for analyzing them because they underestimate the organic energy gap and fail to correctly describe the van der Waals forces. Since the size of these systems prohibits the use of more accurate methods, corrections to those DFT drawbacks are desirable. In this work a combination of a standard DFT calculation with the inclusion of the charging energy (U) of the molecule, calculated from first principles, is presented. Regarding the dispersion forces, incorrect long range interaction is substituted by a van der Waals potential. With these corrections, the C60, benzene, pentacene, TTF and TCNQ/Au(111) interfaces are analyzed, both for single molecules and for a monolayer. The results validate the induced density of interface states model.

Download or read book Electronic Communication in Heterometallated Porphyrin Oligomers written by Jonathan Cremers and published by Springer Nature. This book was released on 2020-02-13 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book cuts across the divisions of organic, inorganic, and physical chemistry. It describes new methods for creating π-conjugated porphyrin oligomers with precisely defined sequences of zinc and copper metal cations, and how EPR spectroscopy was used to investigate the dipolar and exchange coupling between the paramagnetic copper(II) centres. Porphyrins are a group of heterocyclic macrocycle organic compounds that play an important role in our everyday life and can for example be found in blood where they form a red complex with iron (haem). Various metallic elements can be inserted into a porphyrin and changing the coordinated metal is an excellent way to influence the chemical and physical properties of these molecules. Focusing on 3 metals - zinc, magnesium and copper - the author established new methods for creating π-conjugated porphyrin oligomers and lastly presents the synthesis and investigation of two novel porphyrin nanoballs. Giving the template-directed strategy the author developed for constructing these molecules, this work could provide access to other related nano-cages.
