Glancing angle deposition (GLAD) is a physical vapor deposition method in which by exploiting the atomic shadowing at very high vapor incidence angle, a direct and spontaneous growth of columnar thin films (CTF) of a wide range of materials can be attained. The easiness, low cost, and versatility are the main features which make GLAD a promising nanoscale fabrication technique. A controlled shape and in-plane distribution of nanocolumns make the CTFs to play a vital role in number of applications. Particularly, due to enhanced plasmonic activity and interesting optical properties silver CTFs...
