  The Hall scattering factor is formulated using Rode's iterative approach to
solving the Boltzmann transport equation in such a way that it may be easily
computed within the scope of ab-inito calculations. Using this method in
conjunction with density functional theory based calculations, we demonstrate
that the Hall scattering factor in electron-doped Ti2CO2 varies greatly with
temperature and concentration, ranging from 0.2 to around 1.3 for weak magnetic
fields. The electrical transport was modelled primarily using three scattering
mechanisms: piezoelectric scattering, acoustic scattering, and polar optical
phonons. Even though the mobility in this material is primarily limited by
acoustic phonons, piezoelectric scattering also plays an important role which
was not highlighted earlier.
