Not Accessible

Your library or personal account may give you access

Abstract

We used time-resolved spectroscopies in terahertz and visible ranges complemented with Monte-Carlo simulations to assess the connection between ultrafast charge injection and formation and transport of mobile charge carriers in dye-sensitized nano-structured semiconductors.
