Electronic transmission and dwell time on a double barrier system with an accelerating quantum well

• A resonant tunneling device has been described.
• Variational resonant energy has been considered.
• Geometrical effects have been exhibited.

Resonant tunneling quantum structures consist of asymmetric wells and barriers have been investigated to find their optimized geometrical parameters and potential profile by the numerical calculations. The results show that the widths and the depths of the asymmetric wells have a significant effect on the transmission coefficient and the dwell time. The properties exhibited in this work may establish guidance to the device applications.

The transmission and the dwell time of the tunneling structure are determined by the properties of the accelerating well and the central well.Figure optionsDownload as PowerPoint slide
