ABSTRACT=<p>The discovery of superconductivity in infinite-layer nickelates has attracted much attention due to their association to the high-<italic>T</italic><sub><italic>c</italic></sub> cuprates. Cuprate superconductivity was first demonstrated in bulk samples and subsequently in thin films. In the nickelates, however, the situation has been reversed: although surging as a bulk phenomenon, nickelate superconductivity has only been reported in thin films so far. At the same time, the specifics of infinite-layer nickelates yield distinct interface and surface effects that determine their bulk vs thin-film behavior. In this paper, we provide an overview on these important aspects.</p>
