Device Simulation in Nanoelectronic Era

Progress in combining bandstructure calculation and solid-state device simulation is reviewed. Even though the underlying physics in nano-scaled devices has been shifted from classical to quantum mnechanisms. the pur-pose of electronic devices remains the same: to provide switch and amplification for electrical signals. Key fea-tures in the next generation of device simnulators serv-ing both mnicroelectronics and nanoelectronics are pro-jected
