cze Příprava keramiky a sklokeramiky na bázi Sb2Se3 z původních tenkých filmů nanesených na Kaptonové fólii Amorfní tenký film Sb2Se3 na Kaptonové fólii byl krystalizován za kontrolovaných podmínek pomocí kalorimetru. Zkoumání metodou XRD ukázalo intenzivní pás 1D (Sb4Sb6)n s preferenční orientací v závislosti na podmínkách. Ramanova spektroskopie odhalila volným kyslíkem indukovanou krystalizaci Sb2Se3 filmu. Popis krystalizace vede k přesné kinetické predikci během izotermního zpracování a přípravě sklokeramiky s definovaným množstvím krystalické fáze.

eng Preparation of Sb2Se3-based ceramics and glass-ceramics from native thin films deposited on Kapton foil Amorphous Sb2Se3 thin films (200-1500 nm) deposited on Kapton foil were crystallized in controlled environment using the method of direct calorimetric measurement of thin films. X-ray diffraction was used to determine the intensity of the 1D (Sb4Sb6)n ribbons preferential orientation in dependence on the processing conditions: film thickness, energy flux during the pulsed laser deposition (PLD), heating rate, low and high temperature annealing. Lower PLD energy flux combined with higher deposited film thickness (1500 nm) led to increased orientation in the [2 2 1] direction, which is favorable for thin film solar cells application. Raman spectroscopy showed that thermally induced crystallization produces oxide-free Sb2Se3 thin films. Description of the crystallization kinetics led to very accurate kinetic predictions for the isothermal annealing conditions suitable for preparation of glass-ceramics with defined amount of crystalline phase - the predictions were accurate to ~10% of the true (experimentally determined) value.
