    • The barrier height V=200meV is large as compared to the energy range of the lowest subband transport which for the system of Fig. corresponds to the energy E lower than 4.5 meV. The wave functions vanish exponentially in the barriers with a penetration length equal to h/√ 2 m* (V-E ) ≃h/√ 2 m* (V), which equals roughly 1.7 nm. This is small as compared to the width of the channels (64 nm). The effect of the finite barrier is an increased effective width of the channels. The bridge in the structure of Fig. is necessary to allow the channel electrons to reach the ring.
