Chemical properties of bismuth telluride – carbon composites.
Dane BadawczeCarbon nanotubes and amorphous carbon have been introduced into bismuth telluride matrix (in 0.15 and 0.30 wt % ratio) in order to investigate influence of carbon on composite’s thermoelectric properties. Composites with well-dispersed additives have been obtained by sonication and ball-milling. Chemical composition of materials was confirmed by XPS...

Electrical and noise responses of carbon nanotube networks enhanced by UV light for nitrogen dioxide sensing
Dane BadawczeNetworks consisting of randomly oriented carbon nanotubes (CNN) were investigated toward nitrogen dioxide detection by means of electrical and low-frequency noise measurements. UV-activation of CNN layers improved gas sensitivity and reduced the limit of detection, especially by employing 275 nm-LED. This data set includes DC resistance measurements...

Electrical and noise responses of carbon nanotube networks enhanced by UV light for detection of organic gases (ethanol, acetone)
Dane BadawczeCarbon nanotube networks of different optical transparencies were investigated via resistance and 1/f noise measurements for detection of ethanol and acetone. The sensor resistive and noise responses were collected for dark and UV-assisted conditions, revealing the improvement in sensor sensitivity and limit of detection after applying UV light (275...
