The aim of the project was to investigate the role of metal oxide nanorods on patterned Si surfaces. For this purpose, we optimized various parameters like aspect ratio, nanorod density, etc. to study the wetting properties due to interplay between the surface roughness and chemical property. Under this project we developed a contact angle measurement system. Dr. Chetan Prakash Saini did his PhD under this project. The following papers published under this project:
