At what temperature?

[quixote]

Found this graph in the nature article. Looks to be pretty low.

Found this graph in the nature article. Looks to be pretty low.

Then why is this so revolutionary again?

[kcdodd]

Looks like higher current density.

I can't read the chart because of the size. Are you saying the resistivity is not significantly lower than copper at room temp?

[quixote]

For the record, I didn't intend to become the spokesman for this thing, but for the sake of discussion I've made an attempt to put the room temperature resistivity of each line on the graph for you.

Room temperature copper (per wikipedia): 1.678 × 10^-8 ohm meter
Room temperature STO-SL (black bar in graph): 2.5 × 10^-6 ohm meter
Room temperature O-BA-122 SL (red circle thing in graph): 2.8 × 10^-6 ohm meter
Room temperature Co-coped BA-122 single layer (blue triangle thing in graph): 3.8 × 10^-6 ohm meter

Hopefully I did that right. For the record, the y-axis appears to be resistivity in milliohm*centimeters, and the x-axis is temperature in Kelvin. Room temperature is about 294 K, so I just figured out where that intersects the various lines on the graph. Take with grain of salt. Call doctor in morning.

edit:
I should add that if you right-click on the graph and click "open in new tab", you can use the zoom feature on your browser to easily scale it to become readable.
