Nanotechnologies for electrical engineering

Course description

Nanotechnology consists in the investigation and manipulation of matter at a scale of 1 to 100 nanometers (a nanometer is equal to 1 billionth of a meter). It has broad applications across a number of fields including engineering, physics, chemistry, and biology. Examples of nanotechnology applications include nano-sensors, electronic and photonic components for information processing, displays, batteries, solar cells, etc.. The course covers an introduction to nanoscale transport phenomena, and to the light interaction and manipulation at the nanoscale and their applications to electrical engineering. If you are either a master or a PhD student at the University of Naples Federico II and you wish to know more about this course, or to better understand how this course may fit in your study plan, you can send a mail to prof.
