abstract = {Nanostructures elongated perpendicular to their supporting
substrate have attracted attention owing to their ability to
sustain the coherency at the interface with the misfitting
substrate. Here simple qualitative scaling arguments are
used to derive the equilibrium aspect ratio of an elongated
coherent cylindrical nanowire depending on its volume V. It
is found to increase as V1/4. Using the usual law for the
critical radius of nanowires, the maximum aspect ratio of a
coherent nanowire is found to increase linearly with the
lattice misfit, demonstrating that coherent nanowires with
large aspect ratios exist at equilibrium for large misfits.
In addition, it is shown that when the height of the
coherent crystal is limited, a possible equilibrium state
consists of an assembly of non-interacting nanowires.},
