When an electron experiences the force of an electric field … Webthe system Bloch oscillates. Owing to the Zener tunneling the system tends to go the upper energy band and stay there. A single electron tunneling through the junction #1 to the base recovers the system to the lower energy band and the system starts to Bloch oscillate again. This is illustrated in Fig. 4 in the bias point shown in Fig. 3 as an ...
