摘要：

We compare quantum interference devices, exemplified by a resonant tunnel transistor, an Aharonov-Bohm interferometer, and a Y-branch switch, to field-effect transistors regarding their capability to reach fundamentally limited switch energies as well as their normalized transconductance. The resonant tunnel transistor is found to behave similarly to the field-effect transistor (FET). The Aharonov-Bohm interferometer is essentially equivalent to a single-mode Y-branch switch, while the Y branch has an advantage in allowing multimode operation. The normalized transconductance of these two devices can be an order of magnitude larger than for a FET.
