Abstract

We have investigated the anisotropy in electronic transport of the layered ternary Ti₂GeC by comparing the results of measurements on c-axis oriented epitaxial thin-film and polycrystalline bulk samples. The electrical conductivities, Hall coefficients, and magnetoresistances were analyzed within a multi-band framework. An adequate description of the magnetotransport data on the film with the highest mobility required the use of the explicit field-dependent conductivity tensor with three conduction bands. The analysis indicated that n ≈ p, although with n ≈ 3.5 × 10²⁷ m^{- 3}. The ratio of the a- to c-axis conductivities is small and contrary to theoretical predictions.
