| 總結: | In this thesis, we study an electron transport phenomenon observed in silicon
coupled quantum dots called Lifetime-Enhanced Transport. We propose an
energy-dependent tunnelling model to describe this phenomenon that extends
previous works by adding the effects of a finite magnetic field and spin-orbit
interaction. We explore the parameter space of our model through simulations
and show that in certain parameter regimes, Lifetime-Enhanced Transport can
no longer be observed. The simulations demonstrates that sufficiently (1) weak
singlet (coherent) tunnel coupling strength, (2) transparent tunnel barrier and
(3) strong spin-orbit interaction leads to the disappearance of Lifetime-Enhanced
Transport. |
