“…Collective plasmon excitations dephase into electron-hole pairs in the timescale of 10 fs, and the hot carriers should be extracted within the timescale of picoseconds before they recombine nonradiatively – (top panel of Figure d). However, if coupling to a substrate is strong, photo-excitation of the plasmon resonance generates charge-separated states, in which one of the charges is already extracted from the metallic NC (bottom panel of Figure d).…”

We explore the potential of nanocrystals (a term used equivalently to nanoparticles) as building blocks for nanomaterials, and the current advances and open challenges for fundamental science developments and applications. Nanocrystal assemblies are inherently multiscale, and the generation of revolutionary material properties requires a precise understanding of the relationship between structure and function, the former being determined by classical effects and the latter often by quantum effects. With an emphasis on theory and computation, we discuss challenges that hamper current assembly strategies and to what extent nanocrystal assemblies represent thermodynamic equilibrium or kinetically trapped metastable states. We also examine dynamic effects and optimization of assembly protocols. Finally, we discuss promising material functions and examples of their realization with nanocrystal assemblies.

“…Typical strategies to enhance photoresponse include homo/heterojunction induced built-in field, 11–13 gate-induced electrostatic field, 14 polarization induced piezo/ferroelectric field, 15–17 plasmonics induced localized optical field, 18 etc. Ferroelectric modulation holds great promise due to its various inherent advantages, including simplified device fabrication and non-volatility.…”
