Abstract:
The study focuses on exploring the influence of graphene nanoribbon (GNR) width on quantum transport and gas sensing performance. The results indicate that narrower ribbons exhibit stronger quantum confinement, leading to higher sensitivity to gas adsorption, particularly for NH₃. In contrast, wider ribbons demonstrate smoother electronic transport and reduced sensitivity due to weaker confinement effects. The findings highlight the tunability of GNRs, where narrower ribbons are well-suited for gas sensing applications, while wider ribbons provide enhanced transport stability for electronic devices.
