Abstract
Cu microcrystals grown together with whiskers show peculiar morphologies. They strongly tend to exhibit {110}, {100} and {100} when grown from CuI, CuBr and CuCl respectively. Their surface are atomically flat, but they often are covered with thin {111} film of the transport agent (CuX). Having atomically flat surfaces and heights of atomic size, both triangular hills and long straight banks also grow on the surface.
