Topological electric field-defined quantum dots in bilayer graphene: An atomistic approach
Wlodzimierz Jaskolski
We study topological bound states in quantum dots defined by an electric field in bilayer graphene. An external field is perpendicular to the bilayer and changes sign in a finite r…
Gapless states and current control in strongly distorted gated trilayer graphene
Wlodzimierz Jaskolski
We investigate gated trilayer graphene partially devoid of outer layers and forming a system of two trilayers connected by a single layer of graphene. A difference in the stacking…
Existence of nontrivial topologically protected states at grain boundaries in bilayer graphene: signatures and electrical switching
Wlodzimierz Jaskolski, Marta Pelc, Leonor Chico +1
Recent experiments [L. Ju et al., Nature, 2015, 520, 650] confirm the existence of gapless states at domain walls created in gated bilayer graphene, when the sublattice stacking is…
Divacancy-induced Ferromagnetism in Graphene Nanoribbons
W. Jaskolski, Leonor Chico, A. Ayuela
Zigzag graphene nanoribb ons have spin-polarized edges, anti-ferromagnetically coupled in the ground state with total spin zero. Customarily, these ribbons are made ferromagnetic b…
Edge states and flat bands in graphene nanoribbons with arbitrary geometries
W. Jaskolski, A. Ayuela, M. Pelc +2
We prescribe general rules to predict the existence of edge states and zero-energy flat bands in graphene nanoribbons and graphene edges of arbitrary shape. No calculations are nee…
Electron-Hole Correlations and Optical Excitonic Gaps in Quantum-Dot Quantum Wells: Tight-Binding Approach
Rui-Hua Xie, Garnett W. Bryant, Seungwon Lee +1
Electron-hole correlation in quantum-dot quantum wells (QDQW's) is investigated by incorporating Coulomb and exchange interactions into an empirical tight-binding model. Sufficient…
