  • The interfaces between complex oxides can play host to a range of interesting electronic phenomena. Xieet al. demonstrate that the electronic properties at the LaAlO3/SrTiO3interface can be tuned upon application of common polar solvents such as acetone, ethanol and water.

  • The authors experimentally demonstrate the coexistence of superconductivity and ferroelectricity at LaAlO3/KTaO3 interfaces. The superconducting transition temperature is enhanced due to ferroelectric polarization-induced reduction in dielectric constant, which narrows the interfacial potential well, confining carriers closer to the interface.

  • Whether electron–phonon coupling is a generic feature in FeSe/SrTiO3 to enhance superconductivity remains unclear. Here, Zhang et al. report replica bands in FeSe/SrTiO3(110), suggesting a common mechanism in FeSe on SrTiO3with different surface terminations.

  • Studying quantum phase transitions at oxide interfaces provide a key to understand emergent two-dimensional (2D) superconductivity. Here, Chen et al. report comprehensive electronic phase diagram of the 2D electron system at the superconducting LaAlO3/SrTiO3 interface with independent control of carrier density and disorder.

  • Two dimensional electron gases (EG) at the heterointerface of complex oxides show fascinating properties. The authors report on an EG formed at the CaHfO3/SrTiO3 interface independent of interface termination and robust against environmental conditions most likely originating from oxygen non-stoichiometry.

  • Imaging of ferroelectric domain walls and their polarity is achieved through scanning stress microscopy. Twin boundaries are found to allow nanoscale gating of the two-dimensional electron gas at the LaAlO3/SrTiO3 interface.

  • Stable manipulation of polar skyrmions is challenging because of the underlying competitive energy scales. Now thermal excitation has been demonstrated to be an effective way to control such topological states.

  • LaAlO3/KTaO3 interfaces show novel orientation-dependent superconductivity. Here, the authors directly reveal the interfacial electronic structures and suggest that higher superconducting transition is related with stronger electron-phonon coupling.

  • The emergence of conductivity at the {001} interface of LaAlO3 and SrTiO3 is one of the more celebrated examples of interface engineering. Using a microscopy approach based on a sensitive magnetometry probe, it is now shown that narrow paths of enhanced conductivity occur along the crystallographic axes of the oxide structures.

  • The direct observation of in-plane charged domain walls in BiFeO3 ferroelectric films a few nanometres thick, their deterministic creation, manipulation and annihilation by applied voltage, as well the demonstration of their memristive functionality is reported.

  • An enhanced superconducting pairing temperature (Tg) has only been observed in single-layer FeSe interfaced with TiOx system. Here, the authors construct a new interface composed of single-layer FeSe interfaced with LaFeO3 showing a highest Tg of 80 K among all-known interfacial superconductors.

  • Macroscopic properties usually follow algebraic scaling laws near phase transitions. Here, the authors investigate the scaling properties of the metal‐insulator transition at the LaAlO3/SrTiO3 interface, finding that coupling between structural and electronic properties prevents the universal behavior.
