Optical-pump terahertz-probe spectroscopy (OPTP) has been applied to study charge generation, transport and the evolution of the photo-induced excited states in thin film organic semiconductors, with emphasis on their relevance to photovoltaic technology. In these experiments the response of the ...

Optical spectroscopy is increasingly employed for the investigation of complex systems, and femtosecond techniques have been very successful in clearing up the time-dependent dynamics of numerous processes in physics, chemistry, and biology. In the pump-probe scheme, the evolution of quantum level occup...
Using terahertz wave time-domain spectroscopy system,we measured the terahertz wave time-domain spectroscopy of the corn oil between 0.2 and 1.4 THz.Taking care of the effect of the utensil,we employed a novel iterative algorithm to analyze the optical properties of the corn oil.In contrast to ...
