Who can measure the resistivity or carrier density of small samples of GaN?

I am working with small samples of intrinsic gallium nitride, each 10 x 10 x 0.35 mm in size. Non-contact methods are required with GaN such as microwave absorption and Hall effect (e.g. COREMA}. We obtained inconsistent results with microwave absorption because the coil was larger than the sample, and verified that 4-probe methods are not appropriate with GaN. Please help us to make these measurements or refer us to a lab that can do so. I would appreciate any suggestions.
