Further miniaturization of communication devices is bottlenecked by inductor-based oscillators, which potentially could be replaced by spin-torque nano-oscillators (STNOs). Progress is thwarted, however, by the low microwave power delivered by typical STNOs based on trilayer magnetic tunnel junctions. This work proposes to utilize the physics of double-barrier resonant tunneling in an STNO designed for significantly enhanced microwave power and conversion efficiency. This conceptual framework just might provide the spintronic cure for these technological ills.
