Metal Organic Vapour Phase Epitaxy

MOVPE growth of III-nitride materials (doped with magnetic materials) is based on the vapor transport and chemical reactions of the precursors group III alkyls and V group hydrides. The metalorganic sources can be either liquids, such as trimethylgallium (TMGa), trimethylaluminum (TMAl) or solids, like trimethylindium (TMIn).

MOVPE system

Magnetotransport technique is used to measure resistivity, Hall effect, magnetoresistance, etc. The system can be cooled down to 1.2 K and superconducting based magnet reaches 7 T.

Ferromagnetic Resonance

FMR is a spectroscopic technique to probe the magnetization of ferromagnetic materials. It is a standard tool for probing spin waves and spin dynamics.

Point Contact Andreev Reflection

Point-contact spectroscopy (PCS) is an experimental tool used for investigations of the interaction mechanisms between electron-electron, electron-phonon, electron-magnon etc. in metallic systems.

Hall effect set-up

The Hall effect set-up is used to measure resistivity (Van-der-Pauw), mobility of charge carrier and carrier density in semiconductors.

Atomic Force Microscopy

AFM is a scanning probe microscopy technique, in which a nano-scale tip scans the sample surface. The system employs a laser beam detection system, where a laser beam is reflected from the back of the reflective cantilever and detected by a position-sensitive segmented photodiode
