This course will introduce senior undergraduate and beginner postgraduate students to the basic physics of novel miniaturized (mesoscopic and nanoscopic) devices. As the device size is reducing, electrons’ behavior in these devices is changing drastically. As a result, the electrical properties of these devices need to be understood in a more fundamental way. The course would start from the basics of quantum mechanics and equip the students to delve into advanced topics in nanoscale devices.INTENDED AUDIENCE:UG III/IV-year students in Electronics and Communication Engineering/ PG I year students in Microelectronics and VLSI.PRE-REQUISITE:Basic knowledge of electrostatics and classical electron transport theory would be desirable for this course. Nevertheless, the course would build from basics and continue to the advanced topics. INDUSTRY SUPPORT:The following companies might value this course (as it overlaps with their domain, I haven’t had any communication with these companies about the course though): 1. Intel 2. Analog Devices 3. Synopsys
