A brief summary of some of the simulation efforts within the Nanostructure Research Group at Arizona State University is presented, with emphasis on the tools used for modeling deep-submicrometer devices and quantum dot structures under low bias conditions. The results obtained with our 3D drift-diffusion simulator for 0.1 mm n-channel MOSFETs show that the atomistic nature of the impurity atoms has significant influence on the device transfer charac-teristics. In the case of quantum dot structures, we find that the level quantization is preserved even as the dot is opened, but that there is a selection of particular eigenstates that depends strongly on the positions of the contacts
