The electronic properties of a p–i–n diode with a superlattice in the intrinsic region is investigated by optical and electrical measurements. The results of optical study clearly indicate a formation of localized Wannier‐Stark states in the intrinsic region. In addition, the measured derivative of Zener current reveals several peaks which correspond well to the Wannier‐Stark states.These results indicate that the observed peaks arise from Wannier‐Stark resonance of Zener current which has been theoretically predicted.
