Morphology Effectively Controls Singlet-Triplet Exciton Relaxation and Charge Transport in Organic Semiconductors
V. K. Thorsmølle, R. D. Averitt, J. Demsar +7
We present a comparative study of ultrafast photo-conversion dynamics in tetracene (Tc) and pentacene (Pc) single crystals and Pc films using optical pump-probe spectroscopy. Photo…
Magnetic exchange interaction between rare-earth and Mn ions in multiferroic hexagonal manganites
D. Talbayev, A. D. LaForge, S. A. Trugman +4
We report a study of magnetic dynamics in multiferroic hexagonal manganite HoMnO3 by far-infrared spectroscopy. Low-temperature magnetic excitation spectrum of HoMnO3 consists of m…
Comparison of Birefringent Metamaterials and Meanderline Structure as Quarter-Wave Plates at Terahertz Frequencies
Andrew C. Strikwerda, Kebin Fan, Hu Tao +3
We have fabricated a quarter-wave plate from a single layer birefringent metamaterial. For comparison, an appropriately scaled double layer meanderline structure was fabricated. At…
Planar wallpaper group metamaterial for novel terahertz applications
Christopher M. Bingham, Hu Tao, Xianliang Liu +3
We present novel metamaterial structures based upon various planar wallpaper groups, in both hexagonal and square unit cells. An investigation of metamaterials consisting of one, t…
Electronic control of extraordinary terahertz transmission through subwavelength metal hole arrays
Hou-Tong Chen, Hong Lu, Abul K. Azad +5
We describe the electronic control of extraordinary terahertz transmission through subwavelength metal hole arrays fabricated on doped semiconductor substrates. The hybrid metal-se…
A metamaterial absorber for the terahertz regime: Design, fabrication and characterization
Hu Tao, Nathan I. Landy, Christopher M. Bingham +3
We present a metamaterial that acts as a strongly resonant absorber at terahertz frequencies. Our design consists of a bilayer unit cell which allows for maximization of the absorp…
