Abstract
The leakage mechanism of the quasi-superlattice structure was investigated by current-voltage measurements for multilevel charge storage. It was found that the resonant tunneling occurred at around 2, 2.5 and 7V under a gate voltage swept from 0 to 10 V. It was observed that the the leakage current at room temperature remained low when the 10 V gate voltage was applied. It was also found that a negative differential resistance occurred at different gate biases for the measurements of 50 K.
