Surface-modified semiconductor nanoparticle ligands: MerckRecent Research Landscape

Charge carrier recombination at surface defects limits optoelectronic efficiency, which is mitigated by engineering the nanoparticle shell and ligand interface. Precise control over these nanostructures prevents energy loss and enhances device stability.

What technical problems is Merck addressing in Surface-modified semiconductor nanoparticle ligands?

Surface state charge recombination

(3)evidences

Chemical incompatibility between nanoparticle surfaces and surrounding matrices leads to phase separation and performance loss. Stabilizing these interfaces prevents structural degradation and maintains functional integrity.

Unstable nanoparticle surface states

(2)evidences

Uncoordinated surface atoms create electronic traps that dissipate energy. Eliminating these traps prevents non-radiative decay and increases quantum yield.
