These Ossila substrates are soda lime float glass slides carrying a continuous, unpatterned coating of indium tin oxide (ITO) about 100 nm thick. This catalogue item supplies the 25 mm x 25 mm size in a pack of 100, giving researchers a transparent, conductive surface for a broad range of experiments.
The glass is polished and 1.1 mm thick, and the ITO layer is fully oxidized. Ossila quotes a sheet resistance of 20 Ω.□ -1, with measured values of 14 - 20 Ω.□ -1 obtained on its Four-Point Probe System. AFM measurements give a roughness of 1 nm RMS for the bare glass and 1.8 nm RMS for the ITO surface, making the substrates suitable for work where a smooth, flat base matters.
Because the coating covers the whole face, the substrates suit techniques such as scanning tunnelling microscopy, conductive AFM, spectroscopy and electropolymerization, where an electrode pattern is not required.
- Conductive, smooth support for scanning tunnelling microscopy (STM).
- Substrate for conductive atomic force microscopy (AFM) measurements.
- Transparent conductive base for spectroscopy experiments.
- Working electrode surface for electropolymerization studies.
