WebA layer of pure aluminum deposited beneath the aluminum-copper layer acts as a sink for copper and delays hillock formation. Increasing film copper content reduces hillock … A hillock or knoll is a small hill, usually separated from a larger group of hills such as a range. Hillocks are similar in their distribution and size to small mesas or buttes. This particular formation occurs often in Great Britain and China. A similar type of landform in the Scandinavian countries goes by the name ”kulle” or ”bakke” (depending on the country) and is contrary to the above phenomena formed when glaciers polish down hard, crystalline bedrock of gneiss or granites, leavi…
