The International Workshop on Computational Electronics covers all aspects of advanced simulation of electronic transport and optoelectronic processes in semiconductors and semiconductor devices based on both inorganic and organic materials. IWCE 2014 will feature the traditional IWCE topics in electronic transport, thermal transport, spin transport, optoelectronic processes and coupled phenomena. Additionally, we will extend the conference to topics such as first principles calculations in the context of transport studies, and novel architectures for nanodevices. The scientific program, organized in a single-session format, consists of invited lectures, contributed talks, and poster presentations. The workshop is intended to be an international forum for discussions on the current trends and future directions of computational electronics. The emphasis of the contributions is on interdisciplinary aspects of Computational Electronics, touching Physics, Engineering, Applied Mathematics, as well as Chemistry and Biology. Active participation of graduate students, including student presentations, is strongly encouraged.
