2017 01 * Dr. Yoon teaches ECE 3200 (Introduction to Semiconductor Physics)
ECE 3200 is a core course for EE major students. Starting from the fundamental atomic structure, we learn the device operations in details. We plan on inviting industry engineers at the end of the semester to learn about the real life problems in semiconductor industry. The students are very much motivated, and I am very happy to work with the students.

2017 01 * Congratulations to the Dedicated Undergrad Reserachers!
Yoon’s group is building on the dedication and efforts by highly motivated researchers. The work primarily led by three undergrad students (Eric Snyder, Dean Collett, Zijian Wang) has been accepted for the presentation at the MRS Spring meeting (April 17 -21, 2017; Phoenix, Arizona). For this work, Eric Snyder (ECE senior) has developed MATLAB programs to decouple the complicated electron beam signals on topological insulators.
The University of Utah provides UROP program for well-qualified students, and the MRSEC invites summer REU students.
2016 12 * Gathering with WSU students
We welcome the students from Weber State University (Meagan Parker, Nick Allen). The senior students are working with Prof. Kristin Rabosky on the projects of perovskite solar cells and SEM-based characterizations. After the campus / facility tour, Yoon’s group students met them at the cafeteria in the Nanofab. We discussed our projects related to SEM.

2016 11 * Open Positions
Yoon’s Research Group is seeking for new group members (undergraduate, graduate, and post-doc). In particular, we have open RA position(s) for well-qualified Ph.D. students in Fall 2017. Please feel free to contact Prof. Yoon (heayoung.yoon@utah.edu) if you are interested in.
2016 10 * Genie waking up from the long sleep!
Yoon’s research group is grateful for the generous donation of an FESEM through Utah’s Nanofab (Associate Director: Ian Harvey; Engineer: Charles Fisher). The magic touch of the engineers from Hitachi (Ron Ticknor, Ron Gordon, Dan Dinsdale) woke up Genie in 1483 MEB.
Thank you for the great work! Read more
2016 10 * NanoEngineering PV Seminars at the U
