Ever since the discovery of superconductivity in n-doped SrTiO₃ (STO) (10¹⁸ – 10²¹ cm^-3), STO has received significant attention. More recently, it has been shown that superconductivity can be stabilized at much lower concentrations (5.5×10¹⁷ cm^-3) using oxygen-vacancy doped STO raising many questions on the role of dopants and disorder on superconductivity in STO. To-date, these works have been limited to the bulk STO single crystals. In this talk, we will present the first systematic study of superconductivity in epitaxial n-doped Sr_1-xNd_xTiO₃ films grown using hybrid molecular beam epitaxy. We will also discuss the role of dopants, point disorder, and epitaxial strain on the superconductivity and normal state transport in doped STO films.
