Bias-tunable resonances and device metrics in M-graphene nanoribbons

Key Points

• The aim is to explore the electronic transport properties of M-graphene nanoribbons based on edge terminations.
• First-principles calculations were performed on M-graphene nanoribbons with widths ranging from 1 to 4 units.
• Comparison between electronic transport phenomena was made for zigzag and chiral edge terminations.
• Transport characteristics show notable differences between zigzag and chiral edge terminations.
• For specific widths, resonances are tunable by adjusting the bias, impacting device metrics.
