This book provides several examples of how diverse nanofabrication techniques are being used by researchers across the world to fabricate useful materials and devices. A number of research groups present their cutting-edge work on fabricating a variety of nanoscale structures such as split rings, wires, gaps, trenches and holes. The innovative techniques described in this book will be of interest to all who are engaged in research and development of nanofabrication technologies. The book mainly covers application areas in electronics and photonics but the techniques are general enough to be applied to other areas.
