‘Kent Hallman’
“Ultrafast X-ray imaging of the light-induced phase transition in VO2” published in Nature Physics, selected as Spotlight Publication
Jan. 30, 2023—Congratulations to Richard Haglund and Kent Hallman for their Nature Physics publication. This paper is the latest from a multi-year, multi-national (United States, Germany, Denmark, South Korea, France, United Kingdom) collaboration in which Vanderbilt’s part was the preparation and characterization (in conjunction with the Technical University-Berlin) of a challenging ultrathin holographic gold-vanadium dioxide “sandwich” on...
Spotlight Podcast Episode 39: Kent Hallman – using VO2 a phase change material to build photonic devices
May. 7, 2021—This week in the VINSE Spotlight Podcast Kent Hallman tells Alice Leach about using VO2, a phase change material, to build photonic devices. Kent’s paper “Sub-Picosecond Response Time of a Hybrid VO2 :Silicon Waveguide at 1550 nm” was published in Advanced Optical Materials. Kent graduated with a Ph.D. in Physics in 2018.
