Illinois ECE Saturday Engineering for Everyone

Saturday Engineering for Everyone is an open and free lecture series aimed at non-engineers of all backgrounds who are interested in learning about engineering topics.

This talk will be in person at the ECE Building, Room 1002 (Grainger Auditorium).

Speaker: John Dallesasse, Professor of Electrical & Computer Engineering and EDS Distinguished Lecturer

Title: From Bardeen, Brattain, and the Point Contact Transistor to Light Emitting Transistor Structures: A View of the Past and Future Possibilities

This year we celebrate the 75th anniversary of the transistor. The development of this tiny device paved the way for modern electronics, and you probably use transistors every day – they are part of our phones, computers, cameras and even refrigerators. 

Professor Dallesasse will present the history and applications of the transistor, key advances in transistor technology and the potential uses and benefits of newer applications including light-emitting transistors and the transistor-injected quantum cascade laser.

"The observation of electrical gain in a semiconductor device and the explanation of why it occurred is unquestionably one of the most significant technological achievements of the twentieth century. Observing and explaining the transistor effect required the combined experimental genius of Walter Brattain and the theoretical insights of one of the greatest condensed matter physicists, John Bardeen. The initial production of point contact transistors, and the eventual shift to the junction transistor technology initiated by Shockley, were the first steps toward the modern electronics we see today." 

This event is sponsored by the IEEE Electron Devices Society under its Distinguished Lecturer Program.
