Scientists observed trapped electrical charge in an organic semiconductor for the first time.

Cornell scientists are trying to better understand conductivity in organic electronic materials--carbon-based molecules that behave like semiconductors--so they might one day be used for cheap mass-produced electronics, sensors, and solar cells. Using electric-force microscopy, the scientists observed trapped electrical charge in an organic semiconductor for the first time.
