Tailoring pulsed laser deposition fabricated copper oxide film by controlling plasma parameters

Popis výsledku v původním jazyce

The role of oxygen pressure on the structural and physical properties of various copper oxide phases, grown by Pulsed Laser Deposition (PLD) on MgO (100), has been investigated over the pressure range of 1⋅10–5 Pa–1 Pa. Positron annihilation spectroscopy revealed positrons trapped at vacancies and large vacancy clusters with lifetimes ranging from 400 ps to 500 ps. Single copper vacancies VCu, interesting for p-type applications, were found in the CuO phase, whereas in the Cu2O phase copper vacancy complexes coupled with oxygen vacancies (VCu + VO and VCu + 2VO) were seen. Suitable O2 atmosphere conditions, which induced a mixture of copper oxide phases with CuO crystals growing on top of Cu2O films were found.The deposition process was monitored with in situ diagnostic techniques based on Optical Emission Spectroscopy and Langmuir Probe, and enabled identification of kinetic energy ranges for Cu ions, which promote the formation of CuO or Cu2O phases.
