Analytical investigation of channel length influence on organic thin film transistor (OTFT) performance using MATLAB modeling

Organic thin film transistors, which use organic semiconductors as their key component, have emerged as a promising alternative to traditional silicon-based transistors due to their improved conductivity. These transistors offer excellent electrical properties, modifying their properties to meet the requirements of different electronic devices, making them appropriate for utilization in various electronic devices. The process of creating analytical models for organic transistors is being referred to provide a well understanding of their device physics and aid in optimizing their efficiency. For this investigation, we utilized MATLAB to conduct analytical modeling of organic thin film transistors (OTFTs), with the study focused specifically on how changes in the length of the channel impact the output properties of the device. The statement pertains to the simulated output characteristics for channels varying in length from 10µm to 40 µm in size and found that shorter channel lengths resulted in higher drain current. This simulation provides valuable insights into the electrostatic characteristics of the device, which can be used to further improve its efficiency. Therefore, analytical modeling can be a useful tool for obtaining important information about the electrostatic characteristics of the device, which can guide the optimization of its performance.
