Te under Magnetic Field*

We investigate the magnetotransport and thermopower properties in a series of the silver deficient semiconductors Ag_2-δTe (δ = 0, 2×10^-4, and 7×10^-4). We find that the non-trivial field dependences of both the longitudinal and transverse thermoelectric coefficients are sufficiently described by simple expressions that are parameterized with the tangent of the hall angle, defined as tan θ_H ≡ ρ_xy/ρ_xx. While our model is based on the semiclassical transport theory for a single band, it captures intertwined transport characteristics in an explicit manner. We expect our model to have broad applicability in understanding thermoelectric responses as well as electrical transport under high magnetic field in other semimetals and semiconductors.
