Efficient Computation of Kubo Conductivity for Incommensurate 2D Heterostructures
Daniel Massatt, Stephen Carr, Mitchell Luskin
Here we introduce a numerical method for computing conductivity via the Kubo Formula for incommensurate 2D bilayer heterostructures using a tight-binding framework. We begin with d…
Angle-Dependent {\it Ab initio} Low-Energy Hamiltonians for a Relaxed Twisted Bilayer Graphene Heterostructure
Shiang Fang, Stephen Carr, Ziyan Zhu +2
We present efficient angle-dependent low-energy Hamiltonians to describe the properties of the twisted bilayer graphene (tBLG) heterostructure, based on {\it ab initio} calculation…
Modeling and Computation of Kubo Conductivity for 2D Incommensurate Bilayers
Simon Etter, Daniel Massatt, Mitchell Luskin +1
This paper presents a unified approach to the modeling and computation of the Kubo conductivity of incommensurate bilayer heterostructures at finite temperature. Firstly, we derive…
Incommensurate Heterostructures in Momentum Space
Daniel Massatt, Stephen Carr, Mitchell Luskin +1
To make the investigation of electronic structure of incommensurate heterostructures computationally tractable, effective alternatives to Bloch theory must be developed. In Massatt…
