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 × 10 27 m − 3 . The ratio of the a - to c -axis conductivities is small and contrary to theoretical predictions.
