Claims

C1strongest claim

Increasing the confinement restores conveyor-belt operation, which we find to be robust against interface roughness, gate misalignment, and charge defects buried in the oxide. However, our results indicate that defects located at the Si/SiO2-interface can induce considerable orbital excitation. For lower conveyor gate biases, positive defects in the transport channel can even capture passing electrons.

C2weakest assumption

The 3D numerical solutions to the Poisson and time-dependent Schrödinger equations, together with the chosen models of roughness and defects, accurately represent real SiMOS device behavior without significant discretization or modeling errors.

C3one line summary

3D simulations show that high confinement restores robust conveyor-belt shuttling in SiMOS devices despite roughness and buried defects, but Si/SiO2 interface defects cause orbital excitation and can trap electrons at low biases.
