The quantum confinement of strongly correlated electrons in artificial structures provides a platform for studying the behavior of correlated Fermi-liquid states in reduced dimensions. We report the creation and control of two-dimensional electron-liquid states in ultrathin films of SrVO(3) grown on Nb:SrTiO(3) substrates, which are artificial oxide… CONTINUE READING
