Research Interests:
Primary research interests involve transmission electron microscopy (TEM) study of microstructure evolution of solids during irradiation of energetic particles and particle beam modification of materials for engineering applications. The irradiation induced microstructure evolution include the formation of isolated point defects, dislocation loops, voids, gas bubbles, secondary phases, as well as nanocrystallization and solid state amorphization. These changes in themicrostructure greatly affect the physical property of materials. By comparing the effects of irradiations in various materials (metals, semiconductors and ceramics) from various sources (ions, electron, neutrons, a-decay products) at various temperatures, he is seeking a better understanding and control of the irradiation induced microstructure evolution, which involve the thermodynamics and kinetics as well as the roles of various material parameters in the processes. Lumin also has a strong interest in understanding the leaching processes of nuclear waste forms by cross-sectional TEM analysis and irradiation effects on the durability of these waste forms.

Professor Wang's most recent research effort focuses on ion beam modification of materials and irradiation induced nanostructures, especially the formation of 2-D and 3-D ordered nanostructure patterns.
