In the present work, we study the effect of the combined uniaxial -- torsional strain on electronic properties of armchair graphene nanoribbons by using the tight-binding approximation. Our calculations show that under the combined uniaxial -- torsional strain, the semiconductor- metal-semiconductor transition occurs in 8-AGNR. In addition, we can control the band gap of the armchair graphene nanoribbon by its strain. The sensitivity of nanoribbon band gap due to the combined strain makes nanoribbon becoming a promising component for applications in nanoelectromechanical devices.

Presenter: Nguyen Ngoc Hieu
