Keywords: Human brain, Self-assembly, selforganization, information processing at the molecular level, molecular electronics


Molecular electronics will result in enormous gains in device density coupled with reduced power consumption per transistor equaivalent. An important technique in this context is self-assembly. One method for the self-assembly of small molecules to form supramolecular structures was developed, for instance, by Klaus Muellen and coworkers (VALI95). Another crucial element in the future development of circuits for the information processing at the nanoscale and molecular level is the role of the interconnects (ROYC96).

While conventional semiconductor technology follows the top-down principle of further miniaturisation coming from bulk material by improved lithography techniques, the molecular electronics approach is a bottom-up principle, starting from single molecular entities on a nanometer-scale to build information processing networks. That means, ultimate miniaturisation of circuits will be reached if single molecules or atoms can be assembled into active devices that can switch, store and retrieve information. But all these devices would require wires to link the devices, realized with techniques like self-assembly.

This paper gives an overview of what we can learn from the relations of selforganization in the human brain and self-assembly in materials for molecular electronics.
