Complex transition-metal oxides (TMOs) are critical materials for cutting-edge electronics
and energy-related technologies, on the basis of their intriguing properties including …

The growth and characterization of functional oxide thin films that are ferroelectric, magnetic,
or both at the same time are reviewed. The evolution of synthesis techniques and how …

Electrons in correlated insulators are prevented from conducting by Coulomb repulsion
between them. When an insulator-to-metal transition is induced in a correlated insulator by …

The metal-insulator transition in correlated materials is usually coupled to a symmetry-
lowering structural phase transition. This coupling not only complicates the understanding of …

The coexistence of distinct metallic and insulating electronic phases within the same sample
of a perovskite manganite,,,,,, such as La1-xy Pr y Ca x MnO3, presents researchers with a …

The structure of our material world is characterized by a large hierarchy of length scales that
determines material properties and functions. Increasing spatial resolution in optical imaging …

The perovskite manganites with generic formula RE 1− x AE x MnO 3 (RE= rare earth, AE=
Ca, Sr, Ba and Pb) have drawn considerable attention, especially following the discovery of …

Many unusual behaviors in complex oxides are deeply associated with the spontaneous
emergence of microscopic phase separation. Depending on the underlying mechanism, the …

We present a detailed infrared study of the insulator-to-metal transition (IMT) in vanadium
dioxide (VO 2) thin films. Conventional infrared spectroscopy was employed to investigate …

The ground-state properties of correlated electron systems can be extraordinarily sensitive
to external stimuli, offering abundant platforms for functional materials. Using the multi …
