A Life of Physics

Jim Choyke was born in 1926, before the Empire State Building was built, and has lived through many historic conflicts, including World War II and the Cold War. He was 18 when the Army tested the first nuclear bomb and has watched the invention of the internet. Despite his long life, Choyke remains active, driving and walking up three flights of stairs to his office with only the assistance of his cane.

Silicon Carbide: A Compound of the Future

Choyke's fascination with silicon carbide began in the 1950s, long before most others recognized its potential. He spent his career studying the compound's properties as a semiconductor, working at Westinghouse Research Laboratories and later at the University of Pittsburgh. Silicon carbide has a long history in Pittsburgh, dating back to 1891 when Edward Acheson, a Pittsburgh native, discovered it accidentally while trying to create a cheaper alternative to diamonds.

Breakthroughs and Legacy

Choyke's work on silicon carbide has led to numerous breakthroughs, including the discovery of its indirect semiconductor properties. This property has made it indispensable for electroluminescence, battery development, and computer manufacturing. Silicon carbide is also more stable than silicon at high temperatures, making it a crucial material for semiconductors in smartphones and computers.

Industry Impact

Silicon carbide is not only crucial for energy-intensive applications but also has the potential to revolutionize industries such as transportation and energy production. Certain areas of Japan use silicon carbide conductors to power their commuter railway systems, which have been shown to be highly energy-efficient.

Personal Life and Legacy

Choyke's family has been deeply involved in his work, with his children often accompanying him to laboratories and participating in science projects. His children, Peter and Alice, have gone on to pursue careers in science, with Peter becoming the director of molecular imaging at the National Cancer Institute and Alice becoming an emeritus professor at Central European University.

Reflections on a Life of Physics

At 100 years old, Choyke remains committed to his work, driven by his passion for physics and his desire to make a lasting impact. He believes that his contributions to the field will be remembered for generations to come, and he is grateful for the opportunities he has had to work with some of the greatest minds in physics.
