Congratulations to Sunghyun Hwang and Professor Yoon on their IEEE Photonics Technology Letters publication!

Congratulations to IMG Member Sunghyun Hwang and IMG Professor Yong-Kyu Yoon, on their recent publication in the journal IEEE Photonics Technology Letters! In this work, titled, “Silicon Phononic Nanowires Enable Ultra-Low Thermal Conductivity Measured by Raman Spectroscopy”, a novel device structure and precise measurement technique were introduced to assess the thermal conductivity of PnC-supported Si MEMS pixels using vacuum-based Raman spectroscopy. The study revealed remarkably low thermal conductivity in PnC-integrated Si nanowires, with values as low as 1.1W/(m×K) reported successfully.
