Identification by deuterium diffusion of a nitrogen-related deep donor preventing the p-type doping of ZnO
N. Temahuki, F. Jomard, A. Lusson +6
Deuterium diffusion is investigated in nitrogen-doped homoepitaxial ZnO layers. The samples were grown under slightly Zn-rich growth conditions by plasma-assisted molecular beam ep…
Transport of indirect excitons in ZnO quantum wells
Yuliya Kuznetsova, Fedor Fedichkin, Peristera Andreakou +8
We report on spatially- and time-resolved emission measurements and observation of transport of indirect excitons in ZnO/MgZnO wide single quantum wells.
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…
Antiferromagnetic interactions in single crystalline Zn1-xCoxO thin films
P. Sati, C. Deparis, C. Morhain +2
In a rather contradictory situation regarding magnetic data on Co-doped ZnO, we have succeeded in fabricating high-quality single crystalline Zn1-xCoxO (x=0.003-0.07) thin films. T…
