Improving Device Performance of OFET by Changing its Geometry

Organic semiconductors have recently gained significant research interest due to its flexible applications, low fabrication cost, large area and the profound advantages over the existing inorganic semiconductors. Out of this, the parameter that has gained increased research significance is Mobility. Mobility of organic semiconductors are not as good as its inorganic counterparts. Now-a-days organic semiconductors have gained much progress to improve its mobility when compared to inorganic semiconductors. One way to improve mobility is to use multiple gates as comparison to single gate. The results of the proposed research work has clearly demonstrates the comparison between SG-OFET and DG-OFET characteristics and its effects on mobility. Results are also shown that the same effect can be observed in case of inorganic semiconductors. OFET structures are designed and the characteristics are obtained by using SILVACO tool.
