Congratulations to Professor Feng and all past and current members of the HSIC group for this award! Overall, the HSIC group has been awarded 16 patents and has published over 50 papers on the light-emitting transistor and transistor laser. Professor Feng would like to thank all former and current HSIC group members for their efforts.
Congratulations to Mr. Mong-Kai Wu for his paper, “Voltage modulation of a vertical cavity transistor laser via intra-cavity photon-assisted tunneling,” which was placed on the cover of Volume 101, Issue 8 of Applied Physics Letters. Congratulations to Dr. Donald Cheng for winning Best Student Paper at CSMANTECH 2011 for his paper titled, “Type-II DHBTs Microwave Characterization and Metallization Issues”. This paper described the problem of emitter-to-base shorts during the fabrication of Type-II submicron DHBTs. He presented designs of experiment to identify the problem, as well as the solution to the problem. Ultimately, the BE shorts were minimized, and devices were fabricated with room temperature current gain cutoff frequency (fT) up to 680 GHz.

Two great new articles on the transistor laser were published this month! From Compound Semiconductor: “The Transistor Laser: A Radical, Revolutionary Device” and from Optics and Photonics News: “The Metamorphosis of a Transistor into a Laser” Professor Feng gave an invited lecture on the transistor laser at the Hong Kong University of Science and Technology’s Institute for Advanced Study. He covers the history of its invention, the basic physics of operation, current research results, and future expectations for the novel device.

The scholarship was formed through contributions by friends, colleagues, and former students. It was a fitting end to an evening of symposium-style talks, dinner, drinks, and general merrymaking. Please contact Eric Iverson to inquire about pictures of the event. After discovering a flaw in the 160-year-old circuit theory, Han Wui Then’s Transistor Laser research has revised Kirchoff’s current law to account for optical generation/recombination. His research enables a simple and intuitive way to view the relationship between electrons and photons in direct semiconductors. “Transistor-laser breaks Kirchhoff’s Law, rewrites textbooks”: EE Times “Transistor laser rewrites the rules”: Optics.org “Redefining Electrical Current Law With the Transistor Laser”: Science Daily In addition to ECE 447 (Active Microwave Circuit Design), Professor Feng will be joint-teaching a course with Professor K.Y. Cheng. This new course will focus on the physical operation and Green Energy applications of LEDs and Solar Cells. This will be a great opportunity to learn about these two important devices, from two men that worked with some of the most influential inventors in the field of optoelectronic devices. Course webpage coming soon for ECE 498MF (Semiconductor LEDs and Solar Cells). For now, information can be found on the ECE department summary for the course
