Horizontal magnetic tunneling in a field-effect device integrated on silicon

The choice for energy-efficient technologies is not a matter of price choice but it is slowly turning into a matter of heat. A recent work suggests devices fabricated directly on Silicon with magnetic tunnel junctions governed by electric pulses, which means without current and minimizing the problem of overheating.
