They can degrade when exposed to oxygen and moisture.
The "magic" happens because of . In these molecules, carbon atoms form alternating single and double bonds. This creates delocalized π-electrons that can move along the backbone of a polymer chain or between stacked small molecules, allowing for electrical conductivity. 2. Charge Transport: From Bands to Hopping physics of organic semiconductors pdf
Instead of Valence and Conduction bands, we speak of HOMO (Highest Occupied Molecular Orbital) and LUMO (Lowest Unoccupied Molecular Orbital). The energy gap between these two determines the material's optical and electrical properties. They can degrade when exposed to oxygen and moisture
One of the most critical differences in the physics of organic semiconductors is how they interact with light. physics of organic semiconductors pdf
