Abstract
We have investigated the anisotropy in electronic transport of the layered ternary Ti2GeC by comparing the results of measurements on cc-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≈pn≈p, although with n≈3.5×1027m−3. The ratio of the aa- to cc-axis conductivities is small and contrary to theoretical predictions.
