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…
Theoretical investigation of in situ k-restore processes for damaged ultra-low-k dielectrics
A. Förster, C. Wagner, J. Schuster +1
Ultra-low-k (ULK) materials are essential for today's production of integrated circuits (ICs). However, during the manufacturing process the ULK's low dielectric constant (k-value)…
Ab-initio Study of the Trimethylaluminum Atomic Layer Deposition Process on Carbon Nanotubes - An Alternative Initial Step
A. Förster, C. Wagner, J. Schuster +1
Electronic applications of carbon nanotubes (CNTs) require the deposition of dielectric films on the tubes while conserving their excellent electronic properties. In our density fu…
DFT investigations of the piezoresistive effect of carbon nanotubes for sensor application
C. Wagner, J. Schuster, T. Gessner
We investigate the piezoresistive effect of carbon nanotubes (CNTs) within density functional theory (DFT) aiming at application-relevant CNTs. CNTs are excellent candidates for th…
Empirical transport model of strained CNT transistors used for sensor applications
C. Wagner, J. Schuster, T. Gessner
We present an empirical model for the nearballistic transport in carbon nanotube (CNT) transistors used as strain sensors. This model describes the intrinsic effect of strain on th…
Improved recursive Green's function formalism for quasi one-dimensional systems with realistic defects
Fabian Teichert, Andreas Zienert, Jörg Schuster +1
We derive an improved version of the recursive Green's function formalism (RGF), which is a standard tool in the quantum transport theory. We consider the case of disordered quasi…
Strong localization in defective carbon nanotubes: a recursive Green's function study
Fabian Teichert, Andreas Zienert, Jörg Schuster +1
We study the transport properties of defective single-walled armchair carbon nanotubes (CNTs) on a mesoscopic length scale. Monovacancies and divancancies are positioned randomly a…
Influence of defect-induced deformations on electron transport in carbon nanotubes
Fabian Teichert, Christian Wagner, Alexander Croy +1
We theoretically investigate the influence of defect-induced long-range deformations in carbon nanotubes on their electronic transport properties. To this end we perform numerical…
Electronic transport in metallic carbon nanotubes with mixed defects within the strong localization regime
Fabian Teichert, Andreas Zienert, Jörg Schuster +1
We study the electron transport in metallic carbon nanotubes (CNTs) with realistic defects of different types. We focus on large CNTs with many defects in the mesoscopic range. In…
