Intra- and Interlayer Excitonic Fine Structure of the Two-Dimensional Perovskite (PEA)PbI
Patrick Grenzer, Fabian Lie, Klaus H. Eckstein +2
Two-dimensional halide perovskites host strongly bound excitons whose fine structure controls polarization selection rules and radiative recombination, yet several spectral feature…
Onset of Spin Entanglement in Doped Carbon Nanotubes Studied by EPR
Andreas Sperlich, Klaus H. Eckstein, Florian Oberndorfer +5
Nanoscale semiconductors with isolated spin impurities have been touted as promising materials for their potential use at the intersection of quantum, spin, and information technol…
Electronic Structure and Scaling of Coulomb Defects in Carbon Nanotubes from Modified Hückel Calculations
Klaus H. Eckstein, Tobias Hertel
Controlled doping and understanding its underlying microscopic mechanisms is crucial for advancement of nanoscale electronic technologies, especially in semiconducting single-wall…
Trions, Exciton Dynamics and Spectral Modifications in Doped Carbon Nanotubes: A Singular Defect-Driven Mechanism
Klaus H. Eckstein, Pascal Kunkel, Markus Voelckel +2
Doping substantially influences the electronic and photophysical properties of semiconducting single-wall carbon nanotubes (s-SWNTs). Although prior studies have noted that surplus…
Diffusive and Unimolecular Nonradiative Decay of Excited States in Doped Carbon Nanotubes
Klaus H. Eckstein, Pascal Kunkel, Markus Voelckel +4
Doping can profoundly affect the electronic- and optical-structure of semiconductors. Here we address the effect of surplus charges on non-radiative (NR) exciton and trion decay in…
Infrared Study of Charge Carrier Confinement in Doped (6,5) Carbon Nanotubes
Klaus H. Eckstein, Florian Hirsch, Richard Martel +1
Electronic degrees of freedom and their coupling to lattice vibrations in semiconductors can be strongly modified by doping. Accordingly, the addition of surplus charge carriers to…
Quantifying Doping Levels in Carbon Nanotubes by Optical Spectroscopy
Klaus H. Eckstein, Florian Oberndorfer, Melanie M. Achsnich +2
Controlling doping is essential for a successful integration of semiconductor materials into device technologies. However, the assessment of doping levels and the distribution of c…
