Exploiting order and disorder in hybrid inorganic-organic electronics

When electronic devices approach the scale of atoms and molecules, one faces the enormous challenge of controlling the device geometry and preventing detrimental device-to-device variations. In the meantime, truly exciting (quantum) physics arises, which might be harnessed into novel functionality. Here I will show that both highly ordered and highly disordered inorganic-organic structures offer unique test bed systems for novel electronic devices at the nanoscale. I focus on two promising systems: ordered 1D molecular wires and disordered nanoparticle networks. In the 1D molecular wires we have discovered an exceptionally large, room-temperature, small-field magnetoresistance effect [1]. This ultrahigh magnetoresistance effect is ascribed to the dramatic consequence of spin blockade in 1D electron transport. In the nanoparticle networks, we demonstrate, using artificial evolution, that this designless system can be configured into any basic Boolean logic gate with a very high degree of stability and reproducibility [2].
