Mechanism of charge transport in organic solids has been an issue of intensive interests and
debates for over 50 years not only because of the applications in printing electronics but
also because of the great challenges in understanding the electronic processes in complex
systems. With the fast developments of both electronic structure theory and the computational
technology the dream of predicting the charge mobility is now gradually becoming a reality.
This volume describes recent progresses in Prof. Shuai¿s group in developing computational
tools to assess the intrinsic carrier mobility for organic and carbon materials at the
first-principles level. According to the electron-phonon coupling strength the charge
transport mechanism is classified into three different categories namely the localized
hopping model the extended band model and the polaron model. For each of them a
corresponding theoretical approach is developed and implemented into typical examples.
