Honolulu, HI, United States, 2006/08/10 - Organic thin film transistors have attracted a great deal of attention as they are the critical components to fabricate low cost and large area flexible displays and sensors for future application in organic electronics..
owever, the major problem to use organic thin film transistor in logic circuits is the high operating voltage required. Researchers in India believe this problem can be solved by using organic materials with high dielectric constant as gate dielectrics.
Prior to a recent paper by researchers in India there was no organic compound with high permittivity known in the literature. Dr. Shyamal Saha, together with colleague Dipankar Chakravorty, both from the Unit on Nanoscience at the Indian Association for the Cultivation of Science published their findings, titled "One-dimensional organic giant dielectrics" in the July 28, 2006 online edition of Applied Physics Letters.
The dielectric properties of nanomaterials has generated strong interests in the scientific community and nanomaterials having such properties are increasingly being referred to as "nanodielectrics". In general, a nanodielectric would consist of a single or multi-component dielectric possessing nanostructures, the presence of which results in the change of one or several of its dielectric properties.
