P: ECE 745.
Course Prerequisite(s)
Prerequisite knowledge and/or skills
-
ECE 745 or consent of instructor. NOTE: Next offering Fall 2010.
-
Knowledge of fundamentals of quantum mechanics, and a familiarity with semiconductor bandstructure and semiconductor transport is recommended.
Textbook(s) and/or other required material
Recommended:
- M. Lundstrom, "Fundamentals of Carrier Transport"
- D. K. Ferry and S. M. Goodnick, "Transport in Nanostructures"
- S. Datta, "Electronic Transport in Mesoscopic Systems"
- J. H. Davies, "The Physics of Low-Dimensional Semiconductors"
Extensive use of current research literature.
Course objectives
-
Understand the rich physics of electron transport in modern semiconductor structures, in a wide area of operating temperatures (from milli-Kelvin to room temperature), in both 3D and low-dimensional structures (conventional FET devices, heterostructures, quantum wires, quantum dots and single-electron transistors, resonant structures). Become proficient in some of the modern semiconductor modeling techniques (e.g., bulk ensemble Monte Carlo and Usuki mode matching.) Also, another goal is to give students some practice in technical writing and giving technical oral presentations.
Topics covered
NOTE: Course is presently offered in the Spring semester of ODD YEARS.
1) Semiclassical transport:
Boltzmann equation revisited;
Ensemble Monte Carlo solution to the Boltzmann equation;
High field transport: hot carriers, nonequilibrium phonons
2) Transport in nanostructures:
Two-dimensional electron gas (density of states, Landau levels) ;
One-dimensional systems (quantum wires, quantum-point contacts and conductance quantization);
Zero-dimensional systems (quantum dots; single-electron transistor); Decoherence in nanostructures
3) Quantum transport (time permitting):
Many-body effects, Green's functions, density matrices
For more on topics covered, see the
2007 syllabus.
Assessment of student progress toward course objectives
-
Students' progress towards the course objectives will be assessed based on homework (homework assignments are mini-projects), and possibly a take-home midterm and final. Also, on Friday of every week, two students at a time will each give a 20-min Power Point presentation on an assigned topic, usually from current research literature.
Many assignments will require use of a computer, and some proficiency in programming is recommended. Students should feel free to use any software package or programming language to solve the homework problems.
