Quantum transport in graphene nanoribbon networks: complexity reduction by a network decimation algorithm
Tom Simon Rodemund, Fabian Teichert, Martina Hentschel +1
We study electronic quantum transport in graphene nanoribbon (GNR) networks on mesoscopic length scales. We focus on zigzag GNRs and investigate the conductance properties of stati…
Electronic transport through defective semiconducting carbon nanotubes
Fabian Teichert, Andreas Zienert, Jörg Schuster +1
We investigate the electronic transport properties of semiconducting (,) carbon nanotubes (CNTs) on the mesoscopic length scale with arbitrarily distributed realistic defects…
An improved Green's function algorithm applied to quantum transport in carbon nanotubes
Fabian Teichert, Andreas Zienert, Jörg Schuster +1
The renormalization-decimation algorithm (RDA) of López Sancho et al. is used in quantum transport theory to calculate bulk and surface Green's functions. We derive an improved ver…
Nanomechanics of CNTs for Sensor Application
C. Wagner, S. Hartmann, B. Wunderle +3
A nanoscopic simulation for an acceleration sensor is aimed based on the piezoresistive effect of carbon nanotubes (CNTs). Therefore, a compact model is built from density function…
Theoretical investigation of an in situ k-restore process for damaged ultra-low-k materials based on plasma enhanced fragmentation
A. Förster, C. Wagner, S. Gemming +1
We present theoretical investigations of a k-restore process for damaged pourous ultra-low-k (ULK) materials. The process is based on plasma enhanced fragmented silylation precurso…
