We investigate the emergence and topological nature of interface states (IFs) in N-AGNR/-AGNR/N-AGNR heterostructure (AGNRH) segments lacking translational symmetry, focusin…
Room-Temperature Pauli Spin Blockade and Current Rectification in 15-13-15 Armchair Graphene Nanoribbon Heterostructures
David M T Kuo
In this study, we investigate the electronic structures of 13-11-13 and 15-13-15 armchair graphene nanoribbon (AGNR) superlattices (SLs) using a tight-binding model. We demonstrate…
Temperature-Stable Tunneling Current in Serial Double Quantum Dots: Insights from Nonequilibrium Green Functions and Pauli Spin Blockade
David M T Kuo
We theoretically investigate charge transport through serial double quantum dots (SDQDs) with strong electron correlations using nonequilibrium Green's function techniques. In the…
Impact of Valley Degeneracy on Thermoelectric Properties of Zigzag Graphene Nanoribbons with Staggered Sublattice Potentials and Transverse Electric Fields
David M T Kuo
This study investigates the band inversion of flat bands in zigzag graphene nanoribbons (ZGNRs) using a tight-binding model. The band inversion results from symmetry breaking in th…
