Self-assembly of molecules and nanotubes and/or nanowires in nanocell computing devices, and methods for programming same

摘要

An assembly of a NanoCell comprising a disordered array of metallic islands interlinked with molecules between metallic input/output leads and with disordered arrays of molecules and Au islands is disclosed. The NanoCell may function both as a memory device that is programmable post-fabrication. The assembled NanoCells exhibit reproducible switching behavior and at least two types of memory effects at room temperature. The switch-type memory is characteristic of a destructive read while the conductivity-type memory features a nondestructive read. Both types of s memory effects are stable for more than a week at room temperature and bit level ratios (0:1) of the conductivity-type memory have been observed to be as high as 10⁴:1 and reaching 10⁶:1 upon ozone treatment which likely destroys extraneous leakage pathways. The invention demonstrates the efficacy of a disordered
