12:00-12:30 Capacitance reconstruction from measured C- V and direct extraction of Mobility in polymer PFETs using split C-V and I-V Measurements
Main electrical parameters were directly extracted from top-contact organic field effect transistor processed by Reel-to-Reel techniques and can be used for the other different techniques (Inkjet-printing, photolithography, etc.). For that, split capacitance - voltage measurements corrected at low frequency were used to calculate the sheet charge density of the channel and the current-voltage measurements are needed for the extraction.

16:00-16:30 Charge Generation Layer in Stacked Organic Emitting Devices
An effective connection-unit for stacked OLED by using Mg-doped Alq3 and F4–TCNQ doped m-MTDATA is reported. UPS studies demonstrated clearly that the doping of F4-TCNQ induces large band bending at the Mg:Alq3 interface, and hence creates a very thin space charge region of approximately 64 Å. This indicates the significance of F4–TCNQ dopant in the connection-unit.
