Deskripsi

Hall-effect measurements indicate p-type conductivity in bulk, single-crystal strontium titanate (SrTiO3, or STO) samples that were annealed at 1200°C. Room-temperature mobilities above 100 cm2/V s were measured, an order of magnitude higher than those for electrons (5-10 cm2/V s). Average hole densities were in the 109-1010 cm−3 range, consistent with a deep acceptor.
