Electrical properties of single crystals of antimony-doped stannic oxide

Abstract

Single crystals of stannic oxide heavily doped with antimony have been grown from tin vapour and oxygen at 1450°c. Their electrical properties have been studied between 77 and 1100°K. These can be interpreted in terms of optical mode lattice scattering at the higher temperatures, with an impurity scattering contribution below about 300°K. Combining the Hall and Seebeck coefficients leads to an average electron effective mass of 0·13 m0.
