Performance Analysis of Organic p-type and n-type Material based Thin-Film Transistors

Abstract

This paper discusses the possibility of organic circuit design, therefore, this paper, initially begins with organic thin-film transistors (OTFTs) independent performance analysis using Atlas Silvaco 2-D device simulator. Subsequently, performance is compared with experimental reported performance parameters. Where, current-voltage (I-V) characteristics of each p/n device are investigated and observed the average error of 0.8%, and 4.3% for threshold voltage and mobility, respectively. The performance of p-type and n-type material-based devices is compared to validate. In addition to this, CuPc, pentacene, $\mathrm{C}_{8}\mathrm{B}\mathrm{T}\mathrm{B}\mathrm{T}, \mathrm{F}_{16}\mathrm{C}\mathrm{u}\mathrm{P}\mathrm{c}, \mathrm{C}_{60}$, and $\mathrm{Z}\mathrm{n}\mathrm{O}$ material-based devices are discussed using p/n type material combinations to observe the impact of different materials and configurations. Analytical outcomes have also been provided for switching threshold and propagation delay validate the simulation of the devices. The identified high-performance n-type and p-type devices are further used the design of organic flexible digital circuits a lower cost.
