Abstract:
Molecules may be considered as electronic systems, with electrons rapidly moving through molecular orbitals and also by long distances in biological metabolism and photosynthesis. The prospect of incorporating molecules into microelectronic circuits based on silicon and metallic conductors has great potential for enhancing consumer electronics, providing solar energy conversion and permitting new functions not possible with silicon. "All-carbon" molecular junctions consist of organic molecules covalently bonded to conducting carbon contacts, which are thermally stable and compatible with practical applications. [1-2] Strong electronic coupling between aromatic molecules and carbon contacts via conjugated bonds results in transport dominated by molecular structure of the interior of the device rather than that of the contacts. Conductance of the molecular junction is strongly dependent on the presence of dihedral angles and interruption of conjugation within the molecular layer, opening the possibility of "rational design" of electronic behavior. An application in a consumer device for electronic music will be described, [3] as will its potentially broader applications in photonics, [4-5] memory, [6-7] and on-chip energy storage. [6] In addition to microelectronic applications, graphene-modified carbon electrodes have unusually high capacitance with both Faradaic and double layer contributions, and may be valuable in supercapacitors used for large scale energy storage.
