Ab-initio calculations of strain induced relaxed shape armchair graphene nanoribbon
An odd number of zigzag edges in armchair graphene nanoribbons and their mechanical properties (e.g., Young's modulus, Poisson ratio and shear modulus) have potential interest for bandgap engineering in graphene based ...
Valley-dependent Lorentz force and Aharonov-Bohm phase in strained graphene p-n junction
Veselago lens focusing in graphene p-n junction is promising for realizations of new generation electron optics devices. However, the effect of the strain-induced Aharonov-Bohm interference in a p-n junction has not been ...
Berry phase and spin precession without magnetic fields in semiconductor quantum dots
We investigate electric field control of spin manipulation through Berry phase in III-V semiconductor quantum dots. By utilizing degenerate and non-degenerate perturbation theories, we diagonalize the total Hamiltonian of ...
