Abstract: Colloidal nanoplatelets are atomically flat, quasi-two-dimensional sheets of semiconductor
that can exhibit efficient, spectrally pure fluorescence. Despite intense interest in their
properties, the growth mechanism behind their highly anisotropic shape and precise atomicscale
thickness was unclear, and even counter-intuitive for commonly studied nanoplatelets.
Here we will explain how growth kinetics can lead to such materials. Knowledge of this
previously unknown mechanism for controlling shape at the nanoscale can then lead to
broader libraries of quasi-two-dimensional solids.
