Stephen John Pearton

Stephen John Pearton passed away on December 7, 2025, at the age of 68. He was born on January 15, 1957, in Hobart, Tasmania, Australia, to Dennis Gregory Pearton and Margaret Faye Godfrey. Steve graduated with a PhD in Physics from the University of Tasmania in 1981. At the beginning of his graduate studies, he was a recipient of the prestigious Australian Institute of Nuclear Science and Engineering Postgraduate Studentship scholarship, an award given to only two students in Australia per year. After completing his PhD, he spent a year as an experimental officer at the Australian Atomic Energy Commission before joining the University of California, Berkeley, as a Post-Doc in 1982. In 1984, he became a member of the technical staff at AT&T Bell Labs in Murray Hill, New Jersey, where he met fellow technical staff member and eventual wife, Cammy Abernathy. Steve and Cammy moved to Gainesville, Florida, in 1993 after both being hired as full professors in the Materials Science and Engineering department at the University of Florida. He was named a Distinguished Professor in 2001 and assumed Emeritus status upon his retirement in 2020, though he continued to conduct funded research. His career spanned more than four decades and played a pivotal role in shaping semiconductor technology. He was widely recognized for his expertise in plasma etching, ion implantation, ohmic contacts, and the development of materials for high-temperature electronics. His prolific work in these areas helped advance technologies that underpin nearly every aspect of modern life, from computing and energy systems to transportation. He was a recipient of major professional honors, including the J.J. Ebers Award from the Institute of Electrical and Electronics Engineers, the David Adler Lectureship Award in the field of Materials Physics from the American Physical Society, and the Gordon E. Moore Medal for Outstanding Achievement in solid state science and technology awarded by The Electrochemical Society. He was honored as a Fellow by numerous societies, including the American Physical Society (where he was also a Life Member), the American Vacuum Society, IEEE, the Materials Research Society, SPIE, and the Electrochemical Society. He authored over 2000 journal articles, 37 book chapters, and 12 books, and was awarded 19 patents. His published work received over 128,000 citations, and he gave over 250 invited talks at conferences throughout his career. Steve enjoyed a wide variety of hobbies that reflected his desire for knowledge and his competitive spirit. In his early years in Australia, he played cricket, rugby, Australian Rules Football, and achieved a 2nd Dan Blackbelt in Taekwondo. Later in life, his passions included following International Cricket, reading, and being a diehard fan of Florida Gator Sports, especially the volleyball and softball teams. He was also passionate about helping his son Max become the best youth baseball player he could possibly be. He had immense inner strength, a wicked sense of humor, and a deep love for his family and friends. Steve was preceded in death by his mother and father. He is survived by his wife of 32 years, Cammy Abernathy, and his son, Max Pearton. A private burial will be held. A gathering to celebrate Stephen’s life will be announced in the beginning of the new year.
