One step towards faster organic electronics

Experimental evidence that short-range intermolecular aggregation is sufficient for efficient charge transport in conjugated polymers

11-Sep-2015

Organic electronics has many advantages: it is inexpensive, flexible and lightweight. In terms of applications, we are only limited by our imaginations. Their weakness is still speed; plastics conduct a charge slowly, compared to silicon, for instance. A polymer consists of long chains of ...
