Abstract
In this article, the Gaussian density of states (DOSs) in organic semiconductors is taken into account in order to derive a charge-based compact model for high-speed organic transistors. This physics-based analytical solution provides a continues current equation from below to above threshold regions with considering the deep and shallow trap densities in the organic material, power-law mobility model, and contact resistances effects. The proposed model is verified with the experimental data of our fabricated organic permeable base transistor (OPBT) and shows good agreement with the measurements. OPBTs are of great interest as vertical organic transistors and stand out due to their excellent performance, such as low-voltage operation and high transit frequency.
期刊介绍:
IEEE Transactions on Electron Devices publishes original and significant contributions relating to the theory, modeling, design, performance and reliability of electron and ion integrated circuit devices and interconnects, involving insulators, metals, organic materials, micro-plasmas, semiconductors, quantum-effect structures, vacuum devices, and emerging materials with applications in bioelectronics, biomedical electronics, computation, communications, displays, microelectromechanics, imaging, micro-actuators, nanoelectronics, optoelectronics, photovoltaics, power ICs and micro-sensors. Tutorial and review papers on these subjects are also published and occasional special issues appear to present a collection of papers which treat particular areas in more depth and breadth.
