Magnetic Transparent Conductors for Spintronic Applications
Pino D'Amico, Alessandra Catellani, Alice Ruini +4
Transparent Conductors (TCs) exhibit optical transparency and electron conductivity, and are essential for many opto-electronic and photo-voltaic devices. The most common TCs are e…
Quenching of low-energy optical absorption in bilayer CN polytypes
Matteo Zanfrognini, Miki Bonacci, Fulvio Paleari +5
In this work we provide a first principles description of the electronic and optical properties of bilayers CN, with different stacking motifs AB, AB and AA. Starting fro…
Density-functional approach to the band gaps of finite and periodic two-dimensional systems
Alberto Guandalini, Alice Ruini, Esa Räsänen +2
We present an approach based on density-functional theory for the calculation of fundamental gaps of both finite and periodic two-dimensional (2D) electronic systems. The computati…
Multi-wavelength Raman Spectroscopy of Ultra-narrow Nanoribbons Made by Solution-mediated Bottom-up Approach
Daniele Rizzo, Deborah Prezzi, Alice Ruini +10
Here we present a combined experimental and theoretical study of graphene nanoribbons (GNRs), where detailed multi-wavelength Raman measurements are integrated by accurate ab initi…
Probing optical excitations in chevron-like armchair graphene nanoribbons
Richard Denk, Alberto Lodi-Rizzini, Shudong Wang +15
The bottom-up fabrication graphene nanoribbons (GNRs) has opened new opportunities to specifically control their electronic and optical properties by precisely controlling their at…
Accurate tight-binding Hamiltonians: effective tools for electronic transport and optical spectroscopy from first principles
Pino D'Amico, Luis A. Agapito, Alessandra Catellani +5
The calculations of electronic transport coefficients and optical properties require a very dense interpolation of the electronic band structure in reciprocal space that is computa…
