Appl. No.:

13/791881

Inventors:

Brigham Young University - Provo UT, US

Anthony Pearson - Vineyard UT, US

Assignee:

BRIGHAM YOUNG UNIVERSITY - Provo UT

International Classification:

H01L 45/00
G11C 17/16

US Classification:

365 96, 257 2, 438104

Abstract:

A permanent solid state memory device is disclosed. Recording data in the permanent solid state memory device forms voids in a data layer between a first wire array and a second wire array. Wires of the first wire array extend transversely to wires in the second wire array. The material is made of a carbon allotrope such that when current is passed through the carbon allotrope, the carbon is quickly oxidized (burned) leaving a complete gap (void) where the fuse once was. One of the advantages of this method is that the fuse material is fully oxidized in the particular “neck region of the bowtie”, such that there is no material left over from which dendrites can grow. In other embodiments, the data layer is a metal or metal oxide selected from the following metals: Tungsten (W), Rhenium (Rh), Osmium (Os), Iridium (Ir), Molybdenum (Mo), Ruthenium (Ru), Rhodium (Rh), Chromium (Cr), and Manganese (Mn).

Abstract:

A method of producing forests of fibrous solid carbon includes providing a catalyst material over a substrate, forming the catalyst material into catalyst nanoparticles, and reacting carbon monoxide with hydrogen in the presence of the catalyst nanoparticles to form forests of fibrous solid carbon attached to the catalyst nanoparticles. A composition of matter includes an inert material disposed upon a substrate, a plurality of nanoparticles of catalyst material upon the inert material, and a plurality of carbon nanotubes upon the nanoparticles. Some methods of producing a forest of carbon nanotubes include preparing a catalyst surface by depositing an inert material onto stainless steel, and depositing iron onto the inert material. The catalyst surface is placed into a furnace chamber, and the furnace chamber is heated. A mixture of hydrogen and carbon monoxide is provided into the furnace chamber

International Classification:

Abstract:

Recording data in a permanent solid state memory device forms voids in a patterned data layer between a first wire array and a second wire array. Wires of the first wire array extend transversely to wires in the second wire array thus creating a crossbar array. The conductive material in the data layer is made of a carbon allotrope such that when current is passed through the carbon allotrope, the carbon is quickly oxidized (burned) leaving a complete gap (void) where the conductive material (i.e., fuse) once was. One of the advantages of this method is that the fuse material is fully oxidized, such that there is no material left over from which dendrites can grow. A horizontal configuration in which the data layer is a bowtie structure is also disclosed. The conductive material in the data layer of the present systems and methods may be a metal or metal oxide selected from the following metals: Tungsten (W), Rhenium (Rh), Osmium (Os), Iridium (Ir), Molybdenum (Mo), Ruthenium (Ru), Rhodium (Rh), Chromium (Cr), and Manganese (Mn).
