One-dimensional crystals

Another important discovery that changed the field of chemical sensing was the synthesis of single crystal one-dimensional oxide nanowires. These are created by the simple evaporation of the desired commercial metal oxide powders at high temperatures and their condensation at lower temperatures on the substrates. These materials have great potential thanks to their reduced lateral dimensions and single crystal habits, both for fundamental study and for potential nanodevice applications, i.e. the third generation of metal oxide gas sensors.
