In the world of materials science, the term "semiconductor" usually brings to mind rigid silicon wafers and inorganic crystals. However, a revolutionary class of materials——has redefined what electronics can look like. By combining the electrical properties of semiconductors with the mechanical flexibility of plastics, these materials have paved the way for OLED screens, flexible solar cells, and wearable sensors.
When a charge (electron or hole) moves through an organic molecule, it slightly deforms the molecular structure. This combination of a charge and its induced lattice distortion is called a polaron . 3. Optical Physics and Excitons physics of organic semiconductors pdf
The backbone of flexible displays and "electronic skin" sensors. 5. Challenges and the Future Despite their promise, organic semiconductors face hurdles: In the world of materials science, the term
The unique physics of these materials allows for manufacturing techniques that are impossible with silicon, such as and roll-to-roll processing . When a charge (electron or hole) moves through
