Phonon Kinetics at the Solid to Liquid Phase Transition
Alex Davie, Farah Vandrevala, Sara Dampf +7
Terahertz time domain spectroscopy (THz TDS) is used to measure the melting kinetics of fructose molecular crystals. Combining single crystal anisotropy measurements with density f…
Soft Phonon Mode Dynamics in Aurivillius Type Structures
Deepam Maurya, Ali Charkhesht, Sanjeev K. Nayak +11
We report the dynamics of soft phonon modes and their role towards the various structural transformations in Aurivillius materials by employing terahertz frequency-domain spectrosc…
Excitation Mechanisms of Er Optical Centers in GaN Epilayers
D. K. George, M. Hawkins, M. McLaren +4
We report direct evidence of two mechanisms responsible for the excitation of optically active Er3+ ions in GaN epilayers grown by metal-organic chemical vapor deposition. These me…
A Tunable Terahertz Detector Based On Self Assembled Plasmonic Structure on a GaAs 2DEG
Che Jin Bae, Deepu George, Rohit Singh +2
Plasmonic detectors have the potential to provide a method of rapid spectroscopy without the need of moving mirrors or gratings. Previous measurements have demonstrated frequency t…
