Resonant tunneling is studied theoretically in a symmetrical rectangular triple‐barrier structure. Analytical expressions for the transmission coefficient and the resonance conditions are derived. It is found that resonant tunneling with transmission 1 and resonant tunneling with transmission < 1 can occur in the symmetrical triple‐barrier structure. It is confirmed that transmission < 1 at resonance may occur when the outer barrier width is less than about one half of the central barrier width.
