diffusion
- Recent experiments in living cells have observed subdiffusive motion, where the mean squared displacement of a molecule grows sublinearly with time as 〈x2〉∼ tα. Motivated by these experiments, we develop a theory for subdiffusion-limited bimolecular
- This Perspective discusses the phenomenon of trapped-hole diffusion in colloidal semiconductor nanocrystals. Surface charge-carrier traps are ubiquitous in nanocrystals and often dictate the fate of photoexcited carriers. New measurements and
- In contrast to the conventional view that surface-trapped holes in CdS and CdSe nanoparticles are static and immobile, recent experimental and theoretical work has shown that these holes are dynamic and undergo diffusion along the surfaces of these
- Recent transient absorption experiments on CdS nanorods suggest that photoexcited holes rapidly trap to the surface of these particles and then undergo diffusion along the rod surface. In this Letter, we present a semiperiodic density functional
