Self-consistent calculations of coherent tunneling oscillations in asymmetric double quantum wells

Coherent carrier tunneling in asymmetric double quantum well heterostructures is analytically investigated through a self-consistent method of calculation. Longitudinal electric fields are applied to reach the interwell resonance conditions. Exact wave functions in asymmetric double quantum well systems (modified Airy functions) are used to include the electron-hole interaction in the coherent tunneling process. Results are in good agreement with the available previous works.
