Abstract
The etching of Cu(210) by bromine has been investigated using scanning tunn eling microscopy. Cu(210) etches at lower temperatures compared to low-inde x Cu planes resulting in a series of superstructures and stepped planes. In particular, a two-dimensional mesoscopic triangular checkerboard pattern f ormed by Bs etching at low temperatures (600-700 K) is reported for the fir st time, opening up a myriad of possible applications in nano-device fabric ation.
