Lasing in a ZnO waveguide: clear evidence of polaritonic gain obtained by monitoring the continuous exciton screening
Geoffrey Kreyder, Léa Hermet, Pierre Disseix +7
The stimulated emission of exciton-polaritons was proposed as a means of lowering the lasing threshold because it does not require the dissociation of excitons to obtain an electro…
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…
Nature of resonant Raman scattering in ZnCoO films under sub-band excitation
K. A. Avramenko, V. P. Bryksa, V. V. Strelchuk +3
Using the methods of scanning electron (SEM) and atom force microscopy (AFM) as well as photoluminescence (PL) and Raman micro-spectroscopy, we investigated films (…
Influence of s,p-d and s-p exchange couplings on exciton splitting in (Zn,Mn)O
W. Pacuski, J. Suffczynski, P. Osewski +10
This work presents results of near-band gap magnetooptical studies on (Zn,Mn)O epitaxial layers. We observe excitonic transitions in reflectivity and photoluminescence, that shift…
Ferromagnetism in Co-doped ZnO films grown by molecular beam epitaxy: magnetic, electrical and microstructural studies
V. V. Strelchuk, K. A. Avramenko, V. P. Bryksa +7
We studied structural, optical and magnetic properties of high-quality 5 and 15% Co-doped ZnO films grown by plasma-assisted molecular beam epitaxy (MBE) on (0001)-sapphire substra…
Magnetic Anisotropy of Co2+ as Signature of Intrinsic Ferromagnetism in ZnO:Co
P. Sati, R. Hayn, R. Kuzian +8
We report on the magnetic properties of thoroughly characterized Zn1-xCoxO epitaxial thin films, with low Co concentration, x=0.003-0.005. Magnetic and EPR measurements, combined w…
