Simulation of Nanoscale Electronic Systems

As modern silicon integrated devices have reached nanometer scale, device simulation has evolved to provide designers with physical tools that account for particle and quantum features of the transport. At the same time, the ultimate scaling limits of silicon structures are being approached and new material systems have been investigated as candidates to complement or possibly replace silicon technology in the future. Simulation has an important role for the exploration of new molecular device systems, but the increased model complexity presents also many new computational challenges. This chapter will present an overview of simulation approaches for nanoscale device systems with application examples ranging from traditional silicon MOSFETs to molecular and bio-inspired structures.
