    Job ID: #JOB 19/2020

The student will join the Group of Electron Microscopy and Electron Spectroscopy under the supervision of prof. Adrian Kozanecki and dr Ewa Przeździecka, working on the NCN funded project “Pathway to high-efficiency red emission in Eu-doped ZnO-based light sources”. The final aim of the project is to obtain highly efficient red emission from such structures.

The aim of the project in its first stage is optimization of technology of ZnO, ZnMgO and ZnCdO-based quantum structures doped with Eu and grown by molecular beam epitaxy (MBE). To realize this aim it is necessary to determine proper growth conditions which will allow to obtain the structures with very well defined interfaces and without composition gradients. It requires performing precise characterization of the structures with several experimental techniques such as X-ray diffraction, transmission and scanning electron microscopy, and photoluminescence. Secondary ion mass spectrometry will be used to see possible inter-diffusion of Eu ions across the quantum well/barrier interfaces and to control the uniformity of atomic composition. It is expected that the elaborated technology of MBE growth of such structures will be reliable and repeatable. No doubts that some technological solutions will be patented.
