摘要：
We find the true low bound of the size of a critical nucleus of the low-current state in double-barrier resonant tunneling structures. By changing the structural parameters of the device, the critical nucleus size can be made as low as the typical distance between electrons in the well. We thus reaffirm that the decay of the metastable upper current state via the nucleation mechanism can be achieved in resonant tunneling structures.
