摘要:
This invention provides a new procedure for attaching molecules to semiconductor surfaces, in particular silicon. The molecules, which include, but are not limited to porphyrins and ferrocenes, have been previously shown to be attractive candidates for molecular-based information storage. The new attachment procedure is simple, can be completed in short times, requires minimal amounts of material, is compatible with diverse molecular functional groups, and in some instances affords unprecedented attachment motifs. These features greatly enhance the integration of the molecular materials into the processing steps that are needed to create hybrid molecular/semiconductor information storage devices.
摘要:
An electrochemical cell array including an array of silver layers fabricated directly on a substrate, an insulator covering the silver conductor array and a gold array deposited on top of the insulator. Wells are patterned at regions where the gold conductor array overlaps the silver conductor array forming conductor rings in the walls and/or floors of the wells. A molecule can then be coupled to the surface of the one or more conductors in each well.
