There are also other types of semiconductors, like copper oxide, selenium, cadmium sulfide, and lead sulfide. However the properties of these semiconductors are harder to control than those listed above, thus they have few uses in modern electronics.
Carbon in the form of nanotubes or high purity diamond thin films also offers promise as a semiconductor. It should work at much higher temperatures than other semiconductors can, but fabrication problems remain to be solved before it can be used in practical devices.
