Kinetic processes in chalcogenide bulks and thin films - correlation between crystal growth, viscosity and self-diffusion
Provider: Grantová agentura ČR
Programme: Juniorské projekty
Implementation period: 01.01.20 - 31.12.22
Workplace:
Fakulta chemicko-technologická - Katedra fyzikální chemie
Investigator: Barták JaroslavTeam member: Pálka Karel | Martinková Simona
Description:
The project is focused on detailed study of relationship between crystal growth kinetics, viscosity and surface self-diffusion in chalcogenide bulk and thin films amorphous materials. Self-diffusion and viscosity will be studied using surface flattening of micro/nano structures embossed into the surface of prepared samples. Obtained data will be compared with the data gained on bulks using thermomechanical analysis and on both, bulks and thin films, using nanoindentation. Further, volume crystal growth and lateral surface crystal growth in bulk samples, and crystal growth in thin films will be studied using microscopy techniques. The data on crystal growth rates, viscosities and self-diffusion coefficients will be correlated and used for description and prediction of crystallization behavior in the amorphous materials, which is important for preparation, processing and utilization of amorphous materials.
