In semiconductor nanocrystals, the physical effects of deliberately included impurities, called dopants, may depend on the dopant position with the crystal.
Conductive polymers, i.e. plastics, that conduct electricity, are important in science and technology as they offer the potential for cheap, flexible electronic devices.
Hybrid light-emitting devices based on organic semiconductors and inorganic semiconductor nanocrystals are of great interest for applications in optical displays and solid-state light sources.
