Compact model for organic thin-film transistor with Gaussian density of states
AIP Advances, 2015 Developing a compact model for organic thin-film transistors (OTFTs) would be significant for designing organic circuits. Contrasting the traditional silicon transistors, OTFTs are theorized using hopping transport and a Gaussian density of states.
