Qubit energy splitting control by dynamic Stark shift
Superconducting quantum circuits offer similar functionalities as quantum systems created of single atoms, ions, and spins addressed with optical radiation. The main advantage of their superconducting...
Research results | 19.04.2021Magnetic and transport properties of Cu1.05Cr0.89 Mg0.05O2 and Cu0.96Cr0.95 Mg0.05Mn0.04O2 films
We prepared conductive, polycrystalline or amorphous Cu1.05Cr0.89 Mg0.05O2 films on a-plane sapphire substrates by pulsed laser deposition under different O2 partial pressure and substrate temperature....
PublicationsEllipsometry on monolayer films of InAs and AlAs embedded in GaAs and of InP embedded in GaP
Ellipsometric measurements have been made at room temperature on MOVPE-grown InAs monolayers (M). (0.5-1 ML) and AlAs MLs (1 to 12 ML) in GaAs around the GaAs fundamental gap E0(GaAs) and on MOVPE-grown...
PublicationsInP monolayers inserted in a GaP matrix studied by spectroscopic ellipsometry
Ellipsometric measurements on single ultrathin InP layers of 0.5 and 1 monolayer (ML) thickness inserted into GaP by metal-organic vapor phase epitaxy (MOVPE) growth have been carried out at room temperature...
PublicationsMagnetotransport properties of Zn90Mn7.5Cu2.5O100 films
Zn90Mn7.5Cu2.5O100 films have been prepared on a-plane sapphire substrates by pulsed laser deposition. Paramagnetism mainly caused by Mn2+ ions was observed in the films from room temperature down to 2...
PublicationsRoom-temperature cathodoluminescence of n-type ZnO thin films grown by pulsed laser deposition in N-2, N2O, and O-2 background gas
Epitaxial ZnO thin films were grown by pulsed laser deposition (PLD) in N2 or N2O or O2 background gas on MgO-buffered a-plane sapphire. The excitonic room-temperature cathodoluminescence (CL) intensity,...
PublicationsMagnetoresistance in pulsed laser deposited 3d transition metal doped ZnO films
ZnO films with different 3d transition metal doping (Ti, Co, Mn) were prepared by pulsed laser deposition. The occurrence of positive magnetoresistance (MR) was studied in dependence on temperature. Large...
PublicationsLow temperature photoluminescence and infrared dielectric functions of pulsed laser deposited ZnO thin films on silicon
C-axis oriented ZnO thin films were grown on silicon (100) and (111) substrates by pulsed laser deposition. Low temperature photoluminescence spectra show besides the peaks of free excitons, of defect...
PublicationsInfluence of vanadium concentration on the microstructure and magnetic properties of V-doped ZnO thin films
Vanadium doped ZnO thin films (Zn1−xVxO, where x=0.05 or x=0.13) were grown on c-cut sapphire substrates using pulsed laser deposition technique. Their structure and magnetic properties were examined...
PublicationsA comparison between ZnO films doped with 3d and 4f magnetic ions
We present electrical and magnetic properties of ZnO films doped with 3d (Mn) and 4f (Gd or Nd) magnetic ions grown on a-plane Al2O3 substrates. Both for films doped with 3d magnetic ions and for films...
