Numerical Simulation and Characteriation of Pentacene based Organic Thin Film transistors with Top and Bottom Gate Configurations
In this paper, we model the characteristics of top and bottom gate configurations of organic thin film transistors (OTFTs) including top gate top contact (TGTC), top gate bottom contact (TGBC), bottom gate top contact (BGTC) , bottom gate bottom contact (BGBC). The path of charge carriers changes in different geometries which possess difference in the electrical behaivour of the devices. The performances of bottom and top gate pentacene based OTFT devices have been analyzed and their performance parameters like mobility, threshold voltage, sub threshold slope, trans conductance, on off ratio have been extracted and compared.
