Extremely low resistance composition and methods for creating same
The invention pertains to creating new extremely low resistance (“ELR”) materials, which may include high temperature superconducting (“HTS”) materials. In some implementations of the invention, an ELR material may be modified by depositing a layer of modifying material unto the ELR material to form a modified ELR material. The modified ELR material has improved operational characteristics over the ELR material alone. Such operational characteristics may include operating at increased temperatures or carrying additional electrical charge or other operational characteristics. In some implementations of the invention, the ELR material is a cuprate-perovskite, such as, but not limited to YBCO. In some implementations of the invention, the modifying material is a conductive material that bonds easily to oxygen, such as, but not limited to, chromium.
1. A composition comprising:
a first layer comprising YBCO having a surface substantially perpendicular to an a-axis of the YBCO; and
a second layer consisting essentially of chromium, wherein the chromium is bonded to copper atoms and oxygen atoms of the surface of the YBCO of the first layer.
2. A composition comprising:
a first layer comprising YBCO; and
a second layer consisting essentially of chromium, wherein the chromium is bonded to copper atoms and oxygen atoms of a surface of the YBCO of the first layer, wherein the surface is substantially parallel to a c-axis of the YBCO.
3. The composition of claim 2 , wherein the first layer consists essentially of YBCO.
4. The composition of claim 2 , wherein the surface is substantially perpendicular to an a-axis of the YBCO.
5. The composition of claim 2 , wherein the surface is substantially perpendicular to a b-axis of the YBCO.
