摘要：
The resonance tunneling properties of sawtooth triple barrier double-well structures were investigated using the non-equilibrium Green's functions method. The dependence of resonance energies on barrier height and width and well widths was investigated. The tunneling feature of the structure under the electric field was investigated. It has been observed that the transmission probability, resonance tunneling energy, and resonance peak intensity are sensitively dependent on the applied electric field and structure parameters. By choosing the appropriate structure, devices that provide resonance transition at the desired energy can be designed in the desired energy level ranges. Thus, this study can provide a basis for switching and oscillator source nano- device designs.
