Flexible electronics employin organic semiconductors, amorphous and polycrystalline semiconductors have existed for many years. The organic polymer based fexible electronics exhibt extraordinary flexibility,bendability and stretchability.Such excellent mechanical performance enables them to be used in a number of unique applications. They are particularly useful for electronic papers and electronic textiles, although the mobility values are very low in comparison to most inorganic semiconductors. Amorphous silicon nanoparticle and polycrystalline silicon have much higher carrier mobility values than organic polymers. Some of them can also be manufacturered in large areas at relatively low cost.

The ideal materials for high-speed applications are high-mobility materials.This also holds for high-speed flexible electronics. The material list for potential fast flexible electronics includes carbon nanotubes, graphene and a number of single walled carbon nanotubes have very high intrinsic carrier mobility. However, they have been difficult to use owing to the difficult manipulation alignment issues and the difficulty in separating metallic and semiconductor tubes. Graphene is a relatively new material, which exhibits very high mobility values. The lack of bangap is currently the bottleneck preventing it from being used as a useful type of semiconductor.

Single-crystal inorganic semiconductor recently emerged as a very promising semiconductor material for fast flexible electronics. Obtaining these materials in very thin forms has been the key to their practical application. Simply thining down the wafers to the desired thickness is not economic for flexible electronics, particularly large-area electronics and between orientations of the same material, the selective release of some of the layers very thin semiconductors with high mobilites.
