This paper explores how quantum tunneling of electrons is affected by the structure of twisted bilayer graphene (TBG) superlattices. It investigates the impact of factors like twist angle, barrier geometry, and defects on electron transmission. The research is significant because it provides insights into controlling electron transport in TBG, potentially leading to new nanoelectronic and quantum devices.
Key Takeaways
- •Quantum tunneling in TBG superlattices is highly sensitive to parameters like twist angle and barrier geometry.
- •Defects can create tunneling states within transmission gaps and allow for control over Klein tunneling.
- •The research provides insights for designing twist-tunable nanoelectronic and quantum devices.
