UCSB Materials Colloquium 4/16/2010
Overview: Strategies for new functional materials
1. Make a material (new structure,
new composition...) that displays
the function sought (eg.
HgBa2CuO4+, TC = 94 K)
2. Take a known structure type and
tune the composition to achieve the
desired function (eg. PZT)
