Indian Scientists Develop Super-Flexible Composite Semiconductors.
The composite semiconductor is made up of two materials a water-insoluble polymer such as ethyl cellulose that provides flexibility, and indium oxide, a semiconductor which brings in excellent electronic transport properties.
Scientists at the Indian Institute of Science (IISc) have developed a super flexible, composite semiconductor material that can have possible applications in next-generation flexible or curved displays, foldable phones and wearable electronics.
The composite semiconductor is made up of two materials – a water-insoluble polymer such as ethyl cellulose that provides flexibility, and indium oxide, a semiconductor which brings in excellent electronic transport properties.
To design the material, the researchers mixed the polymer with the oxide precursor in such a way that interconnected oxide nanoparticle channels are formed (around phase-separated polymer islands) through which electrons can move from one end of a transistor (source) to the other (drain), ensuring a steady current flow.
The key to form these connected pathways, the researchers found, was the choice of the right kind of water-insoluble polymer that does not mix with the oxide lattice when the oxide semiconductor is being fabricated.
