Edge stability, reconstruction, zero-energy states and magnetism in triangular graphene quantum dots with zigzag edges
Oleksandr Voznyy, Alev Devrim Güçlü, Pawel Potasz +1
We present the results of ab-initio density functional theory based calculations of the stability and reconstruction of zigzag edges in triangular graphene quantum dots. We show th…
Excitonic absorption in gate controlled graphene quantum dots
A. D. Guclu, P. Potasz, P. Hawrylak
We present a theory of excitonic processes in gate controlled graphene quantum dots. The dependence of the energy gap on shape, size and edge for graphene quantum dots with up to a…
Spin and electronic correlations in gated graphene quantum rings
P. Potasz, A. D. Güçlü, P. Hawrylak
We present a theory of graphene quantum rings designed to produce degenerate shells of single particle states close to the Fermi level. We show that populating these shells with ca…
