Abstract

Electrical, mechanical, computing, and/or other devices that include components formed of extremely low resistance (ELR) materials, including, but not limited to, modified ELR materials, layered ELR materials, and new ELR materials, are described.

Claims (27)

1 . A computing device, comprising:

a component formed at least in part of a modified extremely low resistance (ELR) material, wherein the modified ELR material comprises:

a layer of a first ELR material, the first ELR material having a crystalline structure and a principal axis extending along an a-axis of its crystalline structure; and

a layer of a second ELR material, immediately adjacent to and on top of the layer of the first ELR material, the second ELR material also having a crystalline structure and a principal axis extending along an a-axis of its crystalline structure,

wherein the first ELR material and the second ELR material are different from one another.

2 . The computing device of claim 1 , wherein the modified ELR material has improved operating characteristics over those of the first ELR material and the second ELR material.

3 . The computing device of claim 1 , wherein the first ELR material and the second ELR material are different forms of the same ELR material.

4 . The computing device of claim 3 , wherein the first ELR material comprises the same ELR material with a first stoichiometry and the second ELR material comprises the same ELR material with a second stoichiometry different from the first stoichiometry.

5 . The computing device of claim 1 , wherein the first ELR material comprises YBCO and the second ELR material comprises NBCO.

6 . An electrical device, comprising:

a component formed at least in part of a modified extremely low resistance (ELR) material, wherein the modified ELR material comprises:

a layer of a first ELR material, the first ELR material having a crystalline structure and a principal axis extending along an a-axis of its crystalline structure; and

a layer of a second ELR material, immediately adjacent to and on top of the layer of the first ELR material, the second ELR material also having a crystalline structure and a principal axis extending along an a-axis of its crystalline structure,

wherein the first ELR material and the second ELR material are different from one another.

7 . The electrical device of claim 6 , wherein the modified ELR material has improved operating characteristics over those of the first ELR material and the second ELR material.

8 . The electrical device of claim 6 , wherein the first ELR material and the second ELR material are different forms of the same ELR material.

9 . The electrical device of claim 8 , wherein the first ELR material comprises the same ELR material with a first stoichiometry and the second ELR material comprises the same ELR material with a second stoichiometry different from the first stoichiometry.

10 . The electrical device of claim 6 , wherein the first ELR material comprises YBCO and the second ELR material comprises NBCO.

11 . A mechanical device, comprising:

a component formed at least in part of a modified extremely low resistance (ELR) material, wherein the modified ELR material comprises:

a layer of a first ELR material, the first ELR material having a crystalline structure and a principal axis extending along an a-axis of its crystalline structure; and

a layer of a second ELR material, immediately adjacent to and on top of the layer of the first ELR material, the second ELR material also having a crystalline structure and a principal axis extending along an a-axis of its crystalline structure,

wherein the first ELR material and the second ELR material are different from one another.

12 . The mechanical device of claim 11 , wherein the modified ELR material has improved operating characteristics over those of the first ELR material and the second ELR material.

13 . The mechanical device of claim 11 , wherein the first ELR material and the second ELR material are different forms of the same ELR material.

14 . The mechanical device of claim 13 , wherein the first ELR material comprises the same ELR material with a first stoichiometry and the second ELR material comprises the same ELR material with a second stoichiometry different from the first stoichiometry.

15 . The mechanical device of claim 11 , wherein the first ELR material comprises YBCO and the second ELR material comprises NBCO.
