Space-charge-limited current fluctuations in organic semiconductors.
Low-frequency current fluctuations are investigated over a bias range covering Ohmic, trap-filling, and space-charge-limited current regimes in polycrystalline polyacenes. The relative current noise power spectral density S(f) is constant in the Ohmic region, steeply increases at the trap-filling transition region, and decreases in the space-charge-limited-current region. The noise peak at the ...
متن کاملInfluence of diffusion on space-charge-limited current measurements in organic semiconductors
Numerical simulations of current-voltage curves in electron-only devices are used to discuss the influence of charged defects on the information derived from fitting space-charge-limited current models to the data. Charged, acceptor-like defects lead to barriers impeding the flow of electrons in electron-only devices and therefore lead to a reduced current that is similar to the situation where...

متن کاملCharge transport in organic semiconductors.
Modern optoelectronic devices, such as light-emitting diodes, field-effect transistors and organic solar cells require well controlled motion of charges for their efficient operation. The understanding of the processes that determine charge transport is therefore of paramount importance for designing materials with improved structure-property relationships. Before discussing different regimes o...
متن کاملCharge-carrier transport in amorphous organic semiconductors
Organic semiconductors have been extensively studied ever since the successful fabrication of organic light-emitting diodes (OLED).4 2-44 Due to their success, it is becoming increasingly important to understand the theory behind the properties of organic materials. In order to exploit all the advantages of implementing organic materials to construct devices, a detailed understanding of charge-...
