Congratulations to Dr. Cheng-Ying Tsai on his successful PhD defenses entitled “Vertical Carrier Transport Properties and Device Application of InAs/InAsSb Type-II Superlattices and a Water-soluble Lift-off Technology”. Cheng-Ying will join camera team at the Apple Inc. as an R&D hardware engineer. The group would like to gratefully thank Cheng-Ying for his many contributions in the past years, and we wish him continued success in his future scientific work with Apple.

Allison McMinn joins the team

The group welcomes new Ph.D student, Allison McMinn, who obtained her BS in electrical engineering at Southern Illinois University, and has won prestigious Graduate Research Fellowship from NSF and ASU FSE Dean’s Scholarship.

Professor Zhang and other collaborators reported the first electrically injected GeSn semiconductor laser

A paper published in Optica reports the first electrically-injected GeSn MWIR lasers epitaxially grown on Si substrates. It is authored by our group alumnus Prof. Shui-Qing(Fisher) Yu at University of Arkansas and his collaborators from our group, Wilkes University, Dartmouth College, UMASS Boston and Arktonics LLC.

Cheng-Ying Tsai traveling to Apple Inc.

Cheng-Ying Tsai will join Apple Inc. in Cupertino, CA for the spring internship. We are looking forward to have more collaborations with Apple Inc. in the future.
