normal electrode การใช้

• For CAR to occur, electrons of opposite spin must exist at each normal electrode ( so as to form the pair in the superconductor ).
• If the normal material is a ferromagnet this may be guaranteed by creating opposite spin polarization via the application of a magnetic field to normal electrodes of differing coercivity.
• To summarize, splitting water with normal electrodes isn't 100 percent efficient ( probably producing too much heat ), so that can still be optimized which they apparently did.
