Quantum resonant tunneling effect and multi-value logic memory
A novel fabrication process, based on selective wet etching and GaAs air-bridge was developed to produce AlAs/GaAs, AlAs/InAs/GaAs quantum dots double barrier quantum well sub-micron resonant tunneling diodes (RTD), and the peak to valley current ratio could be over 20. A new model of multilevel logic SRAM with RTDs was proposed.
