Dr. David Daughton
Dr. Daughton joined Lake Shore in 2011 to focus on CW THz technology. He began with a close assessment of published research work involving THz. He also met with selected materials researchers and THz scientists to explore their perspectives in applying CW THz to their work.
After initial study, Dr. Daughton used Lake Shore’s in-house THz-TDS system as well as other similar instruments at local institutions to begin exploring selected materials and as a result was able to identify criteria important to the use of CW-THz. Collaborations with academic partners at the Ohio State University and the University of Dayton are underway to explore the use of the CW characterization platform to study collective excitations in electronic and magnetic materials.
Some of the results and observations from Lake Shore’s THz development work have been presented by Dr. Daughton at the 2012 and 2013 International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), the 2013 American Physical Society (APS) March Meeting, and the 2013 American Chemical Society (ACS) Spring Meeting. Most recently, at the 2014 APS March Meeting in Denver, Dr. Daughton presented a paper co-authored with researchers from The Ohio State University, “Continuous wave terahertz spectroscopy of Sr2CrReO6 thin films at cryogenic temperatures and in high magnetic fields.” This paper addressed how temperature-dependent THz spectroscopies have proven useful in characterizing the electronic properties of this novel materials.
