Fundamentals of Current Flow

Sobre este curso

Omitir Sobre este curso

Very different from what is taught in standard courses, "Fundamentals of Current Flow" provides a unified conceptual framework for ballistic and diffusive transport of both electrons and phonons - essential information for understanding nanoelectronic devices.

The traditional description of electronic motion through a solid is based on diffusive transport, which means that the electron takes a random walk from the source to the drain of a transistor, for example. However, modern nanoelectronic devices often have channel lengths comparable to a mean free path so that electrons travel ballistically, or "like a bullet."

Verified students taking this course will be required to complete three (3) proctored exams using the edX online Proctortrack software. To be sure your computer is compatible, see Proctortrack Technical Requirements.

Nanoscience and Technology MicroMasters ®

Fundamentals of Current Flow is one course in a growing suite of unique, 1-credit-hour short courses developed in an edX/Purdue University collaboration. Students may elect to pursue a verified certificate for this specific course alone or as one of the six courses needed for the edX/Purdue MicroMasters® program in Nanoscience and Technology.

For further information and other courses offered, see the Nanoscience and Technology MicroMasters® page. Courses like this can also apply toward a Purdue University MSECE degree for students accepted into the full master’s program.

"This is one of the best courses I ever had. Best wishes to Prof. Datta for being such a wonderful teacher. We want more courses like this in future. " - Mainul28

"Thank you for this amazing course. I had a really good time learning. The course TAs were amazing and of course, Dr. Datta made the subject not only simple but very interesting. I will definitely start reading a book or two on nanoelectronics to improve my grasp of the subject. Hope the next course is just as amazing. " - Surajjoshi666

¿Quién puede hacer este curso?

Lamentablemente, las personas residentes en uno o más de los siguientes países o regiones no podrán registrarse para este curso: Irán, Cuba y la región de Crimea en Ucrania. Si bien edX consiguió licencias de la Oficina de Control de Activos Extranjeros de los EE. UU. (U.S. Office of Foreign Assets Control, OFAC) para ofrecer nuestros cursos a personas en estos países y regiones, las licencias que hemos recibido no son lo suficientemente amplias como para permitirnos dictar este curso en todas las ubicaciones. edX lamenta profundamente que las sanciones estadounidenses impidan que ofrezcamos todos nuestros cursos a cualquier persona, sin importar dónde viva.
