Which field of science is at the forefront in the design of novel materials (biomaterials, semiconductors, energetic materials, etc.) and nanotechnology? I would imagine that physicists and materials scientists work together to achieve the above goals, but can someone describe to me the role of each? What do materials scientists do? What do condensed matter and solid state physicists do? How do they compliment each other in the lab? Is there any other field that leads research in computational materials design and nanotechnology? What would someone major in if they wanted to study this broad topic?
