This study takes a unique approach by investigating the influence of various parameters on charge transport processes in Organic Field Effect Transistor (OFET) models. These parameters include field-effect mobility, disorder, trap existence, threshold voltage, and current ON/OFF ratio. The study utilizes two-dimensional finite element-based device models to explore top-contact OFETs with uniform and unequal mobility zones. Several calibrated simulation standards are developed to replicate the morphological disorder in structure, such as considering variable low mobility zones surrounding contacts. The study also examines the effects of varying the channel length from 10 µm to 50 µm on OFF current, ON current, threshold voltage, and current ON/OFF ratio. Notably, the device's Subthreshold slope remains constant for changes in channel length at 68.87 meV/dec. The current ratio decreases with the increase in work function. The sensitivity of both OFF and ON current increases with a change in work function, reaching a maximum value of 705.09 & 0.080 for a 200 meV change at 50 µm channel length.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
