Electronic structure and carrier mobility in graphdiyne sheet and nanoribbons: theoretical predictions
TL;DR: Using density functional theory coupled with Boltzmann transport equation with relaxation time approximation, the electronic structure is investigated and the charge mobility for a new carbon allotrope, the graphdiyne for both the sheet and nanoribbons is predicted.
Journal ArticleDOI
First-principles prediction of charge mobility in carbon and organic nanomaterials
TL;DR: The recent progresses in developing first-principles methods for predicting the intrinsic charge mobility in carbon and organic nanomaterials, within the framework of Boltzmann transport theory and relaxation time approximation are summarized.
Journal ArticleDOI
Theoretical predictions of size-dependent carrier mobility and polarity in graphene
TL;DR: First-principles density functional theory coupled with deformation potential calculations indicate a strong width-dependent carrier mobility in graphene, which is absent in zigzag-type graphene.
