ABSTRACT
In this letter we discuss the performance of semiconductor electrostatic Aharonov–Bohm interferometers that operate in the diffusive regime. We find that the performance is primarily determined by temperature and carrier concentration, and we have identified the conditions for ‘‘fair,’’ ‘‘good,’’ and ‘‘excellent’’ performance. Our analysis shows that two-dimensional interferometers cannot operate at elevated temperatures but one-dimensional interferometers, on the other hand, could operate at 77 K if the carrier concentration is sufficiently high and the structure is cleverly designed to minimize end reflections.
