Abstract
Gate-tunable Schottky barrier diodes find many applications in logic transistors, photodiodes, and sensors. In this work, the electrical properties of Schottky barrier diodes with graphene/pentacene junctions and additional gates were investigated in detail. The results of modeling equations that considered the ideality factor, series resistance, and effective barrier-height according to the gate bias (Vg) were in good agreement with the experimental results. In addition, the dominant conduction mechanism when the effective barrier-height was controlled by Vg is discussed from the perspective of the temperature-dependent currents in Schottky barrier diodes. This work provides critical information that aids our understanding of gated Schottky diodes with graphene/pentacene junctions, increasing the possible practical applications thereof.
期刊介绍：
The IEEE Journal of the Electron Devices Society (J-EDS) is an open-access, fully electronic scientific journal publishing papers ranging from fundamental to applied research that are scientifically rigorous and relevant to electron devices. The J-EDS publishes original and significant contributions relating to the theory, modelling, 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, nanodevices, optoelectronics, photovoltaics, power IC''s, and micro-sensors. Tutorial and review papers on these subjects are, also, published. And, occasionally special issues with a collection of papers on particular areas in more depth and breadth are, also, published. J-EDS publishes all papers that are judged to be technically valid and original.
