Impact of magnetization and hyperfine field distribution on high magnetoelectric coupling strength in BaTiO-BiFeO multilayers
Johanna K. Jochum, Michael Lorenz, Haraldur P. Gunnlaugsson +7
Understanding the mechanisms of magnetoelectric (ME) coupling within multiferroic structures is paramount from a fundamental as well as an applied point of view. We report here tha…
Identification of Li and V acceptor levels in doped nickel oxide
Robert Karsthof, Holger von Wenckstern, Marius Grundmann
Nickel oxide, in particular in its doped, semiconducting form, is an important component of several optoelectronic devices. Doping NiO is commonly achieved either by incorporation…
Investigating the ranges of (meta)stable phase formation in (InxGa1-x)2O3: Impact of the cation coordination
C. Wouters, C. Sutton, L. M. Ghiringhelli +7
We investigate the phase diagram of the heterostructural solid solution (InxGa1-x)2O3 both computationally, by combining cluster expansion and density functional theory, and experi…
The nickel vacancy acceptor in NiO: doping beyond thermodynamic equilibrium
Robert Karsthof, Arthur Markus Anton, Friedrich Kremer +1
This work reports on temperature-induced out-diffusion and concentration decay of the prominent intrinsic point defect VNi (nickel vacancy) in the wide-gap p-type semiconductor nic…
Nickel oxide-based heterostructures with large band offsets
Robert Karsthof, Holger von Wenckstern, Jesus Zuniga-Perez +2
We present research results on the electronic transport in heterostructures based on p-type nickel oxide (NiO) with the n-type oxide semiconductors zinc oxide (ZnO) and cadmium oxi…
Ultrafast dynamics of hot charge carriers in an oxide semiconductor probed by femtosecond spectroscopic ellipsometry
Steffen Richter, Oliver Herrfurth, Shirly Espinoza +8
Many linked processes occur concurrently in strongly excited semiconductors, such as interband and intraband absorption, scattering of electrons and holes by the heated lattice, Pa…
