Temperature dependences of the conductivity of TiOy monoxides with y <= 1.069 are described by the Bloch–Grüneisen function with Debye temperature 400–480 K, and temperature dependences of the susceptibility include Pauli paramagnetism of conduction electrons. The behavior of conductivity and susceptibility of TiOy with y>= 1.087 is typical of semiconductors with nondegenerate charge carriers obeying Boltzmann statistics. The band gap DeltaE between the valence and conduction bands of TiOy (y>= 1.087) is 0.06–0.17 eV, and effective mass of charge carriers is equal to 7–14 electron masses Полный текст |
