Relativistic corrections to resonant quantum tunnelling through heterostructures
The authors have proposed a transfer matrix method of calculation to compute the relativistic transmission coefficient for tunnelling through Ga1-xAlxAs-GaAs heterostructures. Analytical solutions of a Dirac-type equation as effective mass equation for electrons are obtained and it is found that relativistic corrections to resonant tunnelling through multiple finite quantum well heterostructures give the authors small but significant shifts in the transmittance-voltage characteristics.
