First-principles analysis of the effect of magnetic states on the oxygen vacancy formation energy in doped LaSrCoO perovskite
Wei Wei, Florian Fuchs, Andreas Zienert +2
Oxygen vacancies are critical for determining the electrochemical performance of fast oxygen ion conductors. The perovskite LaSrCoO, known for its excellent mix…
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…
Interaction between carbon nanotubes and metals: Electronic properties, stability, and sensing
F. Fuchs, A. Zienert, C. Wagner +2
The interactions between carbon nanotubes (CNTs) and metal adatoms as well as metal contacts are studied by means of ab initio electronic structure calculations. We show that the e…
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…
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…
