The phonon spectrum shown in Fig. 3 of the Letter contained some minor errors; it should be replaced with Fig. 1 below. The changes do not qualitatively alter the conclusions that the phonon spectra show that the honeycomb crystal is mechanically stable. This error does not affect the "zero-temperature optimization scheme," of which the phonon spectrum calculation is a part. It also does not affect any other results of the Letter, most notably V_HON(r), given in Eq. (6). This potential was derived using the "near-melting scheme," which makes no use of the phonon spectrum calculation. Of course, the Monte Carlo self-assembly results are completely unaffected. Indeed, none of the conclusions of this work are altered in any way.
