Spin-Resolved Self-Doping Tunes the Intrinsic Half-Metallicity of AlN Nanoribbons
TL;DR: In this article, the half-metallic properties of zigzagged aluminium nitride (AlN) nanoribbons have been studied and it has been shown that the properties of AlN ribbons can undergo a transition into semiconducting behavior with application of an electric field or uniaxial strain.
Journal ArticleDOI
The Role of SnO2 Processing on Ionic Distribution in Double-Cation-Double Halide Perovskites.

TL;DR: In this article , a hybrid approach of chemical bath deposition (CBD) and nanoparticle SnO2 substrate processing significantly improves the performance of (FAPbI3) 0.97(MAPbBr3)0.03 by reducing micro-strain in the SNO2 lattice, allowing distribution of K+ from K-Cl treatment of substrates to passivate defects formed at the interface and produce higher current in light and dark environments.
Journal ArticleDOI
Electron propagation along a nanowire: a study in chattering
TL;DR: In this article, the authors present an efficient new approach for the simulation of electron transport along a nanowire, in which they have propagated one hundred thousand trajectories, resulting in chaotic scattering of the electron.
