✦ Synopsis

crograph reveals that the surface is not at all atomically flat on a micrometer scale, but instead exhibits fairly large holes (Fig. 4). The STM images clearly show both atomically flat terraces of up to 100 nm in diameter coexisting with ridges and holes, 10 nm or more in depth (Figs. 5a,b).
