A Ballistic Two-Dimensional Lateral Heterojunction Bipolar Transistor
Leonardo Lucchesi, Gaetano Calogero, Gianluca Fiori +1
We propose and investigate the intrinsically thinnest transistor concept: a monolayer ballistic heterojunction bipolar transistor based on a lateral heterostructure of transition m…
Quantum interference engineering of nanoporous graphene for carbon nanocircuitry
Gaetano Calogero, Isaac Alcón, Nick Papior +2
Bottom-up prepared carbon nanostructures appear as promising platforms for future carbon-based nanoelectronics, due to their atomically precise and versatile structure. An importan…
Removing all periodic boundary conditions: Efficient non-equilibrium Green function calculations
Nick Papior, Gaetano Calogero, Susanne Leitherer +1
We describe a method and its implementation for calculating electronic structure and electron transport without approximating the structure using periodic super-cells. This effecti…
Multi-scale approach to first-principles electron transport beyond 100 nm
Gaetano Calogero, Nick R. Papior, Mohammad Koleini +2
Multi-scale computational approaches are important for studies of novel, low-dimensional electronic devices since they are able to capture the different length-scales involved in t…
Full-scale Simulation of Electron Transport in Nanoporous Graphene: Probing the Talbot Effect
Gaetano Calogero, Nick R. Papior, Bernhard Kretz +3
Designing platforms to control phase-coherence and interference of electron waves is a cornerstone for future quantum electronics, computing or sensing. Nanoporous graphene (NPG) c…
Large-scale tight-binding simulations of quantum transport in ballistic graphene
Gaetano Calogero, Nick R. Papior, Peter Bøggild +1
Graphene has proven to host outstanding mesoscopic effects involving massless Dirac quasiparticles travelling ballistically resulting in the current flow exhibiting light-like beha…
