4. Space-Charge Limited Current (SCLC)

Because organic semiconductors often lack intrinsic carriers (they are nearly intrinsic), injected charges dominate. The current-voltage characteristics are governed by the Mott-Gurney law for SCLC, rather than Ohm's law. physics of organic semiconductors pdf

The defining physical characteristic of OSCs is the formation of delocalized $\pi$-electron systems. Because these electrons are loosely bound, they can be excited across energy gaps typically ranging from 1.5 to 3 eV, placing OSCs in the visible light spectrum regime. However, unlike the rigid lattice of silicon, OSCs are Van der Waals solids; the weak intermolecular forces lead to localized electronic states and significant structural disorder. The physics of organic semiconductors centers on the

1. OLEDs: OLEDs operate by injecting charge carriers into the organic semiconductor material, which then recombine to emit light. The efficiency of OLEDs depends on the balance between electron and hole injection, as well as the charge transport properties of the material.
2. OFETs: OFETs operate by applying a gate voltage to modulate the charge carrier density in the organic semiconductor material. The performance of OFETs depends on the charge transport properties of the material, as well as the interface properties between the material and the gate dielectric.
3. OPVs: OPVs operate by converting light into electrical energy through the excitation of charge carriers in the organic semiconductor material. The efficiency of OPVs depends on the absorption coefficient of the material, as well as the charge transport properties and the interface properties between the material and the electrodes.
