Lisa M. Porter

Lisa Marie Spellman Porter is an American materials scientist who is a Professor of Materials Science at Carnegie Mellon University. She works on new ways to process and characterise electronic materials. She has previously served as president of the American Vacuum Society.

Early life and education
Porter studied materials science at Cornell University. She earned her bachelor's degree in 1989, before moving to North Carolina State University for her graduate studies. She completed her doctorate on silicon carbide in 1993. After earning her doctorate, Porter joined North Carolina State University as a postdoctoral research associate.

Research and career
Porter was appointed to the faculty at Carnegie Mellon University at 1997. Her early research considered the metal contacts for high-power electronic devices and oxide–silicon carbide interfaces. She has since investigated several materials, including transparent conducting films and electrodes as well as organic semiconductors. Her research focusses on the wide bandgap semiconductor gallium oxide. Small amounts of gallium oxide can withstand high electric fields and can be used for highly energy intensive processes. Porter has studied a variety of gallium oxide]polymorphs, including α, β and ε-Ga2O3. In particular, β-Ga2O3 bulk single crystals can be fabricated using low-cost melt-growth methods and can be produced in large wafers.

Porter created the spin-out company SenSevere, which creates chemical sensors based on semi-conductors. The sensors can be used to detect hydrogen in harsh environments, including nuclear reactors and chlorine production cells. When these cells are producing chlorine they produce considerable concentrations of hydrogen, and if this is not removed quickly from the system can result in the formation of hydrogen chloride. In nuclear reactors, hydrogen build up can cause explosions when hydrogen interacts with oxygen and water.
