Joan Redwing
Professor Joan Redwing is an Electronic and Photonic Materials faculty member in the Materials Science and Engineering Department. Dr. Redwing's expertise is in metalorganic chemical vapor deposition (MOCVD) synthesis routes for compound semiconductors, and her research activities focus on two main areas. The first is to explore process/structure/property relationships in wide band-gap semiconductor films. She primarily studies the (Al,Ga,In)N family, which are useful for high brightness UV/visible light emitters, active power electronic components, and high temperature electronics.
Since joining Penn State, Dr.Redwing has initiated a new nanomaterials project in collaboration with Theresa Mayer (Associate Professor, Electrical Engineering, Penn State), Ari Mizel (Assistant Professor, Physics, Penn State), and Suzanne Mohney (Associate Professor, MatSE, Penn State). The group has received a National Science Foundation Grant to study the synthesis and characterization of semiconductor nanowires. Silicon-based nanowires are produced by metal catalyzed vapor phase growth in nanoporous substrates. The process begins by creating a porous alumina membrane by anodization with pore size ranging between 35 and 200 nanometers. The nanoporous membrane serves as a template for metal electrodeposition and nanowire growth via a CVD process.
Prof. Redwing teaches courses in the Materials Science and Engineering and Electrical Engineering departments. She teaches two undergraduate courses: MatSE 450 - Synthesis and Processing of Electronic and Photonic Materials and MatSE 455 - Processing and Characterization of Electronic and Photonic Materials and a graduate course: EE 597 - Semiconductor Characterization. Electrical Engineering and Engineering Science students who would like to minor in Electronic and Photonic Materials can also take the undergraduate courses.
