Doping‐Induced Dielectric Catastrophe Prompts Free‐Carrier Release in Organic Semiconductors
Doping‐Induced Dielectric Catastrophe Prompts Free‐Carrier Release in Organic Semiconductors
The control over material properties attainable through molecular doping is essential to many technological applications of organic semiconductors, such as organic light-emitting diodes or thermoelectrics. These excitonic semiconductors typically reach the degenerate limit only at impurity concentrations of 5-10%, a phenomenon that has been put in relation with the strong …
