Byly připraveny dvě řady chalkogenidových skel o obecném složení : xLiI-xGa2S3-(100-2x)GeS2 a 20LiI-xGa2S3-(100-x)GeS2. Objemové vzorky byly připraveny přímou syntézou z prvků polovodičové čistoty v evakuovaných křemenných ampulích. V připravených vzorcích byla měřena vodivost ve střídavém a stejnosměrném elektrickém poli. Dále byl studován vliv teploty a obsahu LiI na iontovou vodivost. Vzorky byly také analyzovány rentgenovou difrakční analýzou, diferenční skenovaní kalorimetrií, modulovanou diferenční skenovací kalorimetrií a Ramanovou spektroskopií. |

In this diploma thesis the results of synthesis as well as physico-chemical characterization of the two sets of bulk glasses xLiI-xGa2S3-(100-2x)GeS2, where x = 15, 20, 25 and 20LiI-xGa2S3-(100-x)GeS2, where x = 0, 5, 10, 15, 20 are summarized. The bulk glasses were prepared by direct synthesis from elements of semiconductor-purity and LiI compound in cleaned and evacuated quartz ampoules placed in a rocking furnace. Electrical properties of the prepared glasses were studied by impedance spectroscopy and potentiostatic chronoamperometry. The impedance spectroscopy provided the information about total electrical conductivity and the potentiostatic chronoamperometry revealed the electronic (hole) conductivity contribution. Other properties of samples was studied by:X-ray diffraction, DSC (differential scanning calorimetry) and Raman spectroscopy. In addition, the xLiI-xGa2S3-(100-2x)GeS2 glasses were compared with the xAgI-xGa2S3-(100-2x)GeS2 glasses, having been previously studied by our group. |
