- •
The maximum value |SC| for an armchair-edge GSG heterojunction can reach 2000 μV/K.
- •
The charge Seebeck coefficient for armchair-edge GSG heterojunctions can be improved by one order of magnitude compared with that for zigzag-edge GSG heterojunctions.
- •
The transmission coefficient and the charge Seebeck coefficient for GSG heterojunction can be effectively modulated by effective spin–orbit coupling λSO and the potential energy V0.
