An explanation of the increased peak-to-valley (PTV) current ratio for double-barrier resonant tunneling structures (DBRTS’s) operated at low temperatures is proposed. We found that this phenomenon is an inherent property of DBRTS’s, not caused by the suppression of thermionic current over barriers. The energy distributions of electrons at different temperatures result in the variations of peak and valley currents.
