The carrier mobility of organic light-emitting devices(OLED) is studied theoretically. Here, our numerical results demonstrate that relative small space charge density results in the more steady behavior ,which decreases near the interface ,then reachs a final certain value. Moreover, with the increase of characteristic length, the coefficient decreases. It has been demonstrated that the carrier mobility is constant for charge carrier densities typically <1023m-3 at low bias voltages and at room temperature.The hole or electron density has an effect on the carrier mobility and increases with a power law with the charge carrier density >1023m-3 at high bias voltages.and the carrier mobility increases with the temperature up.

MNK Publication was founded in 2012 to upholder revolutionary ideas that would advance the research and practice of business and management. Today, we comply with to advance fresh thinking in latest scientific fields where we think we can make a real difference and growth now also including medical and social care, education,management and engineering.
We offers several opportunities for partnership and tie-up with individual, corporate and organizational level. We are working on the open access platform. Editors, authors, readers, librarians and conference organizer can work together. We are giving open opportunities to all. Our team is always willing to work and collaborate to promote open access publication.
Our Journals provide one of the strongest International open access platform for research communities. Our conference proceeding services provide conference organizers a privileged platform for publishing extended conference papers as journal publications. It is deliberated to disseminate scientific research and to establish long term International collaborations and partnerships with academic communities and conference organizers.
