Biography

Jon Ihlefeld is an Associate Professor in the Materials Science and Engineering and Electrical and Computer Engineering Departments at the University of Virginia. He joined UVa in 2017 following a career at Sandia National Laboratories in Albuquerque, NM where he held positions of Senior, Principal, and Distinguished Member of the Technical Staff in the Materials Science and Engineering Center. His research group studies the linkage between processing, structure, and resulting properties in ferroelectrics, dielectrics, and ion-conducting thin films. His group then utilizes this understanding to enable materials integration resulting in novel electronic, thermal, or optical functionality and devices. This includes demonstration of active phonon transport regulation using ferroelectrics, methods to interrogate nanoscale ferroelectric domain structure in active devices, property enhancement via improved material integration, and fast ion conducting thin films for energy storage, among others.

MSE 3101: Materials Science Investigations
Credits: 3
The course amplifies topics covered in introductory materials science through laboratory demonstration and experimentation. An understanding of modern instruments and experimental techniques including x-ray diffraction, optical and electron microscopy is gained through lecture and laboratory experience. Experimental determination of the processing, structure, property relationship is emphasized. Laboratory report writing skills are developed. Prerequisite: MSE 2090
ECE 4501: Special Topics in Electrical and Computer Engineering
Credits: 1–4
A fourth-level undergraduate course covering a topic not normally covered in the course offerings. The topic usually reflects new developments in the electrical and computer engineering field. Offering is based on student and faculty interests.
MSE 4592: Special Topics in Materials Science
Credits: 3

MSE 6592: Topics in Material Science
Credits: 3
A study of special subjects related to developments in materials science under the direction of members of the staff. Offered as required under the guidance of a faculty member.
MSE 7140: Physics of Materials
Credits: 3
Basic course dealing with the physical principles governing the thermal, electronic, optical and magnetic properties of engineering materials. The approach integrates the fundamentals of materials science with essential concepts in solid state and condensed matter physics. Special attention is given to understanding the nature of the crystalline state and wave-particle diffraction with a strong emphasis on the reciprocal lattice concept. Thermal properties are approached by discussing the Einstein and Debye solids and the concept of lattice waves and phonons. The elements of Boltzmann, Bose-Einstein and Fermi-Dirac statistics are reviewed leading to the development of an electron theory of solids. The concepts of Fermi surface and Fermi energy, Brillouin zones, valence and conduction bands are discussed extensively. The atomic origin of magnetism and magnetic effects in solids are analyzed as well as magnetic hysteresis and technical magnetic properties. The fundamental electrical and magnetic properties of superconductors are discussed including the new high Tc ceramic materials. Prerequisite: MSE 6140 or equivalent or instructor permission.
