One-Dimensional Electron Transport Layers for Perovskite Solar Cells [PDF]

Nanomaterials, 2017
The electron diffusion length (Ln) is smaller than the hole diffusion length (Lp) in many halide perovskite semiconductors meaning that the use of ordered one-dimensional (1D) structures such as nanowires (NWs) and nanotubes (NTs) as electron transport layers (ETLs) is a promising method of achieving high performance halide perovskite solar cells ...

Stochastic webs and quantum transport in superlattices : an introductory review. [PDF]

, 2009
Stochastic webs were discovered, first by Arnold for multi-dimensional Hamiltonian systems, and later byChernikov et al. for the low-dimensional case. Generated by weak perturbations, they consist of thread-like regions of chaotic dynamics in phase space.

Role of electron-electron scattering on spin transport in single layer graphene

AIP Advances, 2014
In this work, the effect of electron-electron scattering on spin transport in single layer graphene is studied using semi-classical Monte Carlo simulation. The D’yakonov-P’erel mechanism is considered for spin relaxation.
