Transport properties for 60nm thick layers prepared by the laser ablation from Bi₂Te₃ target and deposited on quartz glass substrates were explored. The energy density of the laser beam on the target was 2Jcm^-2 and temperature of the substrate varied between (20-480^oC) for different samples. The influence of temperature of substrate during the deposition on topography of layers measured by STM (Scanning Tunnelling Microscope) is presented.

Transportní vlastnosti 60nm tlustých vrstev připravených laserovou ablací z Bi₂Te₃ terčíku na křemenné substráty byly prozkoumány. Hustota energie laserového svazku byla 2Jcm^-2 a teplota substrátu se měnila v rozsahu 20-480°C pro různé vzorky. Prezentován je i vliv teploty substrátu na topografii vrstev měřenou pomocí STM (Rastrovací Tunelový Mikroskop).
