Efficient Time-Domain Approach for Linear Response Functions
Michel Panhans, Frank Ortmann
We derive the general Kubo formula in a form that solely utilizes the time evolution of displacement operators. The derivation is based on the decomposition of the linear response…
Top Dielectric Induced Ambipolarity in an n-channel dual-gated Organic Field Effect Transistor
Kaushik Bairagi, Elisabetta Zuccatti, Francesco Calavalle +6
The realization of both p-type and n-type operations in a single organic field effect transistor (OFET) is critical for simplifying the design of complex organic circuits. Typicall…
Linear Scaling Quantum Transport Methodologies
Zheyong Fan, Jose Hugo Garcia, Aron W. Cummings +5
In recent years, predictive computational modeling has become a cornerstone for the study of fundamental electronic, optical, and thermal properties in complex forms of condensed m…
Pseudospin-driven spin relaxation mechanism in graphene
Dinh Van Tuan, Frank Ortmann, David Soriano +2
The possibility of transporting spin information over long distances in graphene, owing to its small intrinsic spin-orbit coupling (SOC) and the absence of hyperfine interaction, h…
Unconventional Features in the Quantum Hall Regime of Disordered Graphene: Percolating Impurity States and Hall Conductance Quantization
Nicolas Leconte, Frank Ortmann, Alessandro Cresti +1
We report on the formation of critical states in disordered graphene, at the origin of variable and unconventional transport properties in the quantum Hall regime, such as a zero-e…
Spin Dynamics and Relaxation in Graphene Dictated by Electron-hole Puddles
Dinh Van Tuan, Frank Ortmann, Aron W. Cummings +2
The understanding of spin dynamics and relaxation mechanisms in clean graphene and the upper time and length scales on which spin devices can operate are prerequisites to realizing…
