A large number of ternary Heusler compounds have been recently proposed as three-dimensional topological insulators with tunable physical properties. However, no transport measurements associated with the topological surface states have been observed in these candidates due to the dominating conduction contribution from bulk. In this work, we investigate the physical properties of sputter deposited topologically non-trivial half-Heusler non-centrosymmetric semimetal YPdBi thin films. First measurements indicate fingerprints of Weak Antilocalization effects and a superconducting phase transition at roughly 4K.
