Of Organic Semiconductors Pdf ((new)) — Physics

Organic semiconductors are used in a variety of electronic devices, including OLEDs, OFETs, and OPVs. The operation of these devices depends on the physics of charge transport and the properties of the organic semiconductor materials.

When an OSC absorbs a photon, it creates an exciton—a bound electron-hole pair. In inorganic semiconductors, the high dielectric constant ($\varepsilon_r$) screens the Coulomb attraction, resulting in Wannier-Mott excitons with large radii and low binding energy ($\sim$ meV), which dissociate easily at room temperature. physics of organic semiconductors pdf

Before diving into the mathematics, one must understand the structural dichotomy. Inorganic semiconductors form covalent networks that are strong and directional. Organic semiconductors, however, are held together by π-conjugated systems . Organic semiconductors are used in a variety of
