Abstract

The present invention includes a chemical monolayer construction that comprises: (a) a substrate having a contact surface; and (b) a plurality of substantially parallel molecular units, wherein said molecular units are attached to said substrate so as to be strongly coupled electronically to said substrate, such as through a conjugated bond. The present invention also includes electronic circuit components and devices including a chemical monolayer construction of the present invention.

Claims (10)

1. A memory device comprising;

a rigid support;

a substrate disposed on said rigid support, said substrate having a contact surface;

a monolayer of a plurality of substantially parallel molecular units having first and second ends, said molecular units attached through their first ends to said contact surface through a conjugated bond such that at least a portion of said substrate and at least one said molecular unit share delocalized electrons, wherein said second ends define a scan surface, and wherein said molecular units can be changed between a first memory state and a second memory state; and

a read-write device adapted to move along said scan surface and adapted to stimulate a change of said molecular units between said first and second memory states, and to determine a memory state status of regions on said scan surface.

2. A memory device comprising:

a rigid support;

a substrate disposed on said rigid support, said substrate having a contact surface;

a monolayer of a plurality of substantially parallel molecular units having first and second ends, said molecular units attached through their first ends to said contact surface so as to be strongly coupled electronically to said substrate such that at least a portion of said substrate and at least one said molecular unit share delocalized electrons, wherein said second ends define a scan surface, and wherein said molecular units can be changed between a first memory state and a second memory state; and

a read-write device adapted to move along said scan surface and adapted to stimulate a change of said molecular units between said first and second memory states, and to determine a memory state status of regions on said scan surface.
