2017 05 * Welcome David!
We are happy to have a new group member, David Magginetti. David is a PhD student in the Department of Materials Science Engineering. He is a past recipient of Wayne Brown Fellowship at the University of Utah. His research focuses on the interface properties of hybrid nano/micro materials and devices. Welcome David!
2017 04 Material Research Society Conference
Yoon’s group gave a presentation at the Materials Research Society conference. The work is conducted in close collaborations with Dr. Kyu-Bum Han, Dr. Jeffery Aguiar, Dr. Brian van Devener, Prof. Vikram Deshpade, and Prof. Taylor Spark.
2017 04 * Dean wins Senior Project Award
The Technical Open-House is one of the exciting events in the ECE department at the University of Utah. All ECE students must complete a senior project to meet graduation requirements. One-year long senior projects are presented in the conference with students, faculty, and sponsors from industry and national labs.

Dean gave a final presentation at the Technical Open-House and won the award (Outstanding Electrical Engineering Senior Project).
Dean, lots of Congratulations!!
We are proud of you.

2017 03 * Invited Seminar at Utah State University
Dr. Yoon gave an invited seminar in the ECE department at Utah State University. It was a good opportunity to meet graduate students and to learn about exciting research work at USU (such as Prof. Reyhan Baktur‘s project integrating transparent antenna on solar cells).
2017 03 * Poster presenation at the GRC (Nanomaterials for Applications in Energy Technology)
Yoon’s research group presents a poster at the Gordon Research Conference. “Nanoscale Local Characterizations of Thin-Film CdTe Solar Cells” by Dean Collett (UofU), Jeffery Aguiar (Idaho National Lab), Brian van Devener (Utah’s Nanofab), Yohan Yoon (NIST), Paul Haney (NIST), and Heayoung Yoon.
The conference was full of exciting talks related to energy technology. See here for the details.
2017 02 * Receiving Nanofab’s Seed Grant
We thank Utah’s Nanofab for the generous support. The Utah’s Nanofab provides state-of-the-art fabrication tools and characterization systems. In particular, the dual detectors equipped in the STEM/EDX offer over 10X higher sensitivity than in a conventional system. It is one to the best EDX systems in the country. This year, a brand new EBSD system with a SSD was installed in the surface characterization lab.
We are very excited working with the tools to investigate the local properties of thin-film solar cells!
STEM: Scanning Tunneling Electron Microscopy
EDX: Energy Dispersive X-ray Spectroscopy
EBSD: Electron Backscattered Diffraction

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.
