Organic semiconductor composites: influence of additives on the transient photocurrent

Creator:

Day, Jonathan, Platt, Andrew D., Ostroverkhova, Oksana, Subramanian, Sankar, and Anthony, John E.

Abstract:

We report on the effect of various guest molecules added to a functionalized anthradithiophene (ADT) host on photoexcited charge carrier dynamics in solution-deposited thin films, from ~100 ps to >100 μs after photoexcitation with 100 fs laser pulses. An addition of 2 and 5 wt % of C60 to a...

On the photoresponse of several novel oligoacene and anthradithiophene derivatives

Creator:

Day, Jonathan

Abstract:

The results of an investigation into carrier dynamics in several novel functionalized and solution-processable pentacene and anthradithiophene derivatives are reported. Measurements were made of real-time photoresponse of polycrystalline thin films of these materials to ultrafast laser pulses, on picosecond to microsecond time-scales, as well as measurements of dark current and...
