Summary on Grant Application Form
We propose to upgrade an existing, successful but outdated, crystal growth facility in the Cavendish Laboratory, to support research programmes on quantum critical metals and oxides. The centrepiece of the facility will be a state-of-the-art, fully transistorised, radio-frequency generator that is an improvement over our existing system in that it: is safe, is more stable, spans a wide range of frequencies, will provide significantly higher power levels, and can be computer controlled. This will be combined with a novel vertical float zone/electrotransport (VFZ/ET) system, the prototype of which was developed in Cambridge. The new crystal growth facility will be used initially to grow high quality single crystals of quantum critical metals which will be used to study non-Fermi liquid behaviour and unconventional superconductivity. Both are very sensitive to crystal quality, and intrinsic behaviour can only be seen in the highest quality crystals. We will use the VFZ/ET system to produce higher quality starting materials; we will also attempt to grow metallic oxides (building on early, partial successes in this area); and finally we will demonstrate our capability to produce large single crystals for neutron scattering work which is very important to the study of quantum critical metals. In parallel, we propose to develop a simple tube furnace that will be based on induction heating; this may be of commercial interest to existing users of induction heaters, and researchers who need tube furnaces that can work at very high temperatures in high vacuum or oxidising environments.
