Field emission from organic materials
… begins by creating a field emitter out of organic conductors-a class of materials mostly neglected to date for this application. The organic emitter is made by copying a non-lithographic template. The process takes 5 minutes, occurs at room temperature and at atmospheric pressure, and does …

End-capped oligothiophene dimers incorporating TTF, metal dithiolene and spirocentric cores
The field of organic conductors and semiconductors has grown rapidly. The development of devices based on this technology, and the insights it provides into molecular electronics have led it to the forefront of materials research both industrially and academically. Electroactive organic species can …

Novel supramolecular assemblies based on sulfur-nitrogen radicals.
… radicals. A general discussion of the history of organic conductors and magnets, and the terms involved in some of the techniques used is given in order to provide a background to the work presented. The second chapter outlines the synthesis and general characterisation of all the dithiadiazolyl …

Ponto crítico quântico supercondutor em sistemas multi-bandas
… study, driven by experiments on the cuprate superconductors, heavy fermions' materials, organic conductors and related compounds. Nevertheless, the transitions involving superconducting phases are not as well explored theoretically as transitions involving magnetic phases. Thus, the study of …

Charge Transport Physics of Organic Semiconductors at High Carrier Densities
The charge transport physics of organic semiconductors has been studied intensively since the discovery of electrical conduction in doped polyacetylene by Heeger, MacDiarmid, and Shirakawa. While the charge transport physics in this class of materials at low carrier densities of less than 10¹⁸ to …

Novel oligomeric and polymeric materials based upon the dibenzotetraaza[14]annulenes.
… the following three categories; liquid crystals, organic conductors, and chelating systems. Additionally the chemistry involved with the synthesis of these types of materials was interesting in its own right and provided a platform for the author to increase his own knowledge of chemistry. The …
