Geometry effects in topologically confined bilayer graphene loops
New Journal of Physics, 2021 We investigate the electronic confinement in bilayer graphene by topological loops of different shapes. These loops are created by lateral gates acting via gap inversion on the two graphene sheets. For large-area loops the spectrum is well described by a

Quantum Networks: Dynamics of Open Nanostructures [PDF]
VLSI Design, 1998 The superposition principle makes quantum networks behave very differently from their classical counterparts: We discuss how local and non‐local coherence are generated and how these may affect the function of composite systems. Numerical examples concern quantum trajectories, quantum noise and quantum parallelism.

Nonlinear Electrical Properties of One-Dimensional Nanostructures [PDF]
, 2009 A general method is first reported for reliably fabricating highly-ordered conventional superconductor nanowire arrays, with good control over nanowire cross section (down to 10 nm by 11 nm) and length (up to 200 microns).

Tunneling theory for a bilayer graphene quantum dot’s single- and two-electron states
New Journal of Physics, 2022 The tuneability and control of quantum nanostructures in two-dimensional materials offer promising perspectives for their use in future electronics. It is hence necessary to analyze quantum transport in such nanostructures.

Quantum confinement in Si and Ge nanostructures [PDF]
Journal of Applied Physics, 2012 We apply perturbative effective mass theory as a broadly applicable theoretical model for quantum confinement (QC) in all Si and Ge nanostructures including quantum wells (QWs), wires (Q-wires), and dots (QDs). Within the limits of strong, medium, and weak QC, valence and conduction band edge energy levels (VBM and CBM) were calculated as a function of
