Semiconductor Terahertz Physics

A rich range of physical phenomena exhibit frequencies in the range of 0.1–10 THz. Within semiconductors, these include phononic, electronic, and mixed modes of oscillations. These fundamental phenomena then serve as the basis for specific devices to produce, manipulate, and detect terahertz radiation.     

Site-selective multi-emitter gold-silver metallopolymers: A novel class of self-assembled materials

New luminescent heterometallopolymers [(Au-C₆F₅)_m(AgOSO₂CF₃)_n (PVP)] with different Au:Ag molar ratios were synthesized. The luminescent emissions of these polymers are strongly dependent on the temperature, excitation wavelengths, and the Au(I):Ag(I) molar ratio. The incorporation of a precise amount of Ag(I) atoms in the backbone of [(Au-C₆F₅)_m(PVP)] metallopolymer allows a controlled tuning of the emission energy in the green-blue range.
