About the Instructor
Supriyo Datta received his B.Tech. from the Indian Institute of Technology in Kharagpur, India in 1975 and his Ph.D. from the University of Illinois at Urbana-Champaign in 1979. In 1981, he joined Purdue University, where he is (since 1999) the Thomas Duncan Distinguished Professor in the School of Electrical and Computer Engineering. He started his career in the field of ultrasonics and was selected by the Ultrasonics group as its outstanding young engineer to receive an IEEE Centennial Key to the Future Award and by the ASEE to receive the Terman Award for his book on Surface Acoustic Wave Devices.
Since 1985 he has focused on current flow in nanoscale electronic devices and the approach pioneered by his group for the description of quantum transport, combining the non-equilibrium Green function (NEGF) formalism of many-body physics with the Landauer formalism from mesoscopic physics, has been widely adopted in the field of nanoelectronics. This is described in his books Electronic Transport in Mesoscopic Systems (Cambridge 1995) and Quantum Transport: Atom to Transistor (Cambridge 2005) and he was elected to the US National Academy of Engineering (NAE) for this work.
Datta is also well-known for his contributions to spin electronics and molecular electronics. He has received Technical Field Awards from the IEEE both for research and for graduate teaching and was selected by Sigma Xi to receive the Procter Prize (http://www.sigmaxi.org/programs/prizes/procter.datta.shtml).
The problem of current flow involves many fundamental issues of non-equilibrium statistical mechanics and with this in mind, Datta’s latest book Lessons from Nanoelectronics: A New Perspective on Transport (World Scientific 2012) tries to make the insights gained from nanoelectronics accessible to a broader audience ( http://nanohub.org/groups/lnebook ).
FUNDAMENTALS OF NANOELECTRONICS – QUANTUM MODELS
A free two-part series of online courses covering the basic concepts and quantum models of nanoelectronics
For Part 1: Basic Concepts, please visit: https://nanohub.org/courses/FON1
Prof. Supriyo Datta presented nanoHUB-U’s first online courses in Spring 2012: Two 5-week courses refined and condensed from his original 2-semester (30 weeks) course on Nanoelectronics and Quantum Transport at Purdue University.
Nearly a thousand students registered for these courses, and the feedback was overwhelmingly positive:
“The course was just awesome…. and Prof Datta’s style of delivering lecture is mind blowing.”
Over 35% of those registered went on to complete the exams and receive proofs of completion and digital badges.
We have now made these courses available in self-paced format.
This course is intended to be broadly accessible to students in any branch of science or engineering.
Quantum Models assumes basic familiarity with calculus, elementary differential equations, and familiarity with matrix algebra.
NO prior acquaintance with quantum mechanics is assumed.

Nanoelectronic devices are an integral part of our life, including the billion-plus transistors in every smartphone, each of which has an active region that is only a few hundred atoms in length.
Fundamentals of Nanoelectronics – Quantum Models, is a unique course developed at Purdue designed to convey the new concepts that have emerged since 1985, which constitute the fundamentals of nanoelectronics and mesoscopic physics.
Even with NO prior background in quantum mechanics, you should learn about cutting-edge developments and concepts that will prepare you for research in nanoelectronics.
Indeed we hope you will be excited to join the field and help invent the new devices that will shape the electronics of this century and meet its challenges.
