course syllabus




This course focuses on the fundamental concepts and principles of nanoelectronic materials and devices. Nanoelectronics is concerned with electronic devices with one or more dimensions at nanoscale. The lecture will cover the electronic properties of solids including semiconductors in samples of physical dimension of ~100 nm or less, and the corresponding basic device building blocks such as quantum dot (QD), single electron transistor (SET), nanowire, carbon nanotube (CNT), graphene, etc. The course will consider the design and analysis of a variety of nanoscale devices ("quantum" or "mesoscopic" devices) and examine the most notable, novel applications.
