Avantama N-21X-Flex

Avantama N-21X-Flex optimizes the low work function nanoparticle solution Avantama N-21X for laboratory-scale applications. It can reliably perform a range of functions from electron injection and transportation to hole blocking and charge recombination irrespective of the overarching device architecture. This is true across the full range of Avantama N-21X-Flex’s potential markets.

If your laboratory application requires a nanoparticle solution with a higher work function and similarly enhanced electrical conductivity, consider Avantama N-20X-Flex. Otherwise, contact us directly with any questions.
