Research Abstract

Photouinduced control of conducting and dielectric properties have been investigated by using steady state terahertz (THz)time domain spectroscopy and transient (optical pump-THz probe)spectroscopy. Target materials were organic conductors (α-(ET)_2I_3, κ-(ET)_2Cu_2(CN)_3)and transition metal oxides (LaCoO_3, LuFe_2O_4).
