This book is primarily intended to be a text book for Bachelor/Master Degree students of Science, Engineering, and Technology. This book has a special role to play in the curriculum of all branches of Science, Engineering, and Technology and will hopefully present valuable guidelines to young graduates. Chapter 1 gives an introduction for surfaces and interfaces. In Chapter 2 we discuss about the thin film and coating. Chapter 3 explains about physical vapour deposition techniques. In Chapter 4, atomic layer deposition and chemical bath deposition are explained. Chapter 5 gives ideas about anti-reflective coating, self-cleaning surfaces and nanoindentation. The book surface science and thin film technology provide the detailed information about the properties of surfaces, types and preparation of thin films. This book will be a reference source for Bachelor Degree Students of Science, Engineering and Technology.
