We have performed measurements of current-voltage characteristics at low temperatures in p-i-n diodes with a thin intrinsic region containing several (GaAs)5/(AlAs)2 quantum wells. Under reverse bias, we found an oscillatory structure in the second derivative of the Zener tunneling current. The measurements agree well with theoretical calculations that are based on a transfer matrix approach and a realistic multi-band and multi-channel tight-binding scattering theory. The experiments show that Wannier-Stark oscillations in semiconductors occur in the d.c. current, in the regime of interband tunneling.
