We have investigated the electronic structures of LaBi and LuBi, employingthe full-potential all electron method as implemented in Wien2k. Using this, wehave studied in detail both the bulk and the surface states of these materials.From our band structure calculations we find that LuBi, like LaBi, is acompensated semi-metal with almost equal and sizable electron and hole pockets.In analogy with experimental evidence in LaBi, we thus predict that LuBi willalso be a candidate for extremely large magneto-resistance (XMR), which shouldbe of immense technological interest. Our calculations reveal that LaBi,despite being gapless in the bulk spectrum, displays the characteristicfeatures of a $\mathbb{Z}_{2}$ topological semi-metal, resulting in gaplessDirac cones on the surface, whereas LuBi only shows avoided band inversion inthe bulk and is thus a conventional compensated semi-metal with extremely largemagneto-resistance.
