- •
The energy gaps and the conductance for ASiNRs can be effectively modulated by effective spin–orbit coupling λSO and the potential energy V0.
- •
An energy gap appears for 8-ASiNR in the presence of V0.
- •
The conductance plateaus for three systems can survive for small and moderate Anderson disorder strengths.
