Upcoming Physics Challenges for Device Modeling

Science and technology at the nanoscale size offer today fundamental challenges in the field of device modeling. In this paper we document the growing interest of academies, institutions, and industries and the present impact on the market, and discuss different design strategies that have been proposed and/or implemented, aimed at the practical realization of innovative nanodevices. Few main examples of ideas and devices, namely ion-channel nano-biosensors, biomimetic sensors, molecular devices, solid-state com-ponents for quantum computation, nanotube electronics, and non-volatile nanomemo-ries, are also revised. 1 Making it small makes the difference There is a large consensus among scientists about the fact that when something (ma-terial, device, system or process) is developed on a truly nanometric scale (1-10 nm) its properties and behavior become different from those observed on the sub-micron mesoscale (10-100 nm). For this reason nanoscience and nanotechnology nowadays of-fer challenging problems from the point of view of fundamental research, and new field
