Dr. Felix A. Buot obtained his M.S.E.E. (Microelectronics) from Stanford University and his Ph. D. (Theoretical Solid-State Physics) from the University of Oregon with Research Assistantship under Profs. G. H. Wannier and J. W. McClure. His Ph.D. thesis deals with the "Theory of Diamagnetism of Bismuth and Bi-Sb Alloys" (Cited as an outstanding Ph.D. Thesis in the Summary of 1970 International Conference on Semimetals and Narrow Band-Gap Semiconductors, Dallas, TX). He was awarded Postdoctoral Research Associateships and Fellowships in the following institutions: (a) Department of Mathematics, Westfield College, University of London, U.K.; (b) International Center for Theoretical Physics (ICTP), Trieste, Italy; (c) Eaton Electronics Research Laboratory, McGill University, Montreal, Canada; (d) Department of Physics, St. Francis Xavier University, Nova Scotia, Canada; (e) Stanford Electronics Laboratory, Stanford University; (f) Laboratory of Atomic and Solid-State Physics (LASSP) and later jointly with the National Research and Resource Facility for Submicron Structures (NRRFSS), Cornell University, Ithaca, NY. He was a Professorial Lecturer, Graduate School, University of the Philippines, and a Science Education Consultant to the Philippines National Science Development Board (NSDB). From 1982 - 2003, he was a Research Physicist working at the U. S. Naval Research Laboratory (NRL), initially as a contractor for about a year. He leads the NRL efforts on time-dependent quantum transport physics, nanoelectronic device theory and simulation. This leads to their first successful time-dependent numerical simulation of GaAs/AlGaAs resonant tunneling diode, which results in their discovery of the autonomous current oscillation of this device in the THz range, when biased in the negative differential resistance region. He has served as a consultant to various universities in the U.S. and abroad. He pioneered the lattice Weyl transform and Wigner discrete phase-space distribution-function technique in quantum dynamics of band electrons in solids. More recently, he formulated the nonequilibrium quantum super-field theoretical (NQSF) technique in quantum transport physics including quasi-particle pairing transport dynamics. Using NQSF, he also formulated the single and multiband nonequilibrium spin quantum transport physics.
