Special Issue Information

Dear Colleagues,

In recent years, perovskite compounds, with their interplay of charge, spin, and orbital ordering, are one of the most largely studied class of materials, both for the investigation of their fundamental properties and for the application of their many functionalities in different fields. Developments of the physical vapor deposition techniques used to deposit perovskite thin films have opened the way to the growth of single-layer thin films, heterostructures, and superlattices with structural properties comparable to those of single crystals. The exploitation of the different mechanisms present at the artificial boundaries with the substrate or with different layers (epitaxial strain, strain relaxation, cation redistribution, selective doping, polar discontinuity, electronic charhe transfer, etc.) has opened up the possibility to modify, in a controlled way, the final physical properties of perovskite thin film-based systems.

An incredibly large number of uses of such systems have been proposed in many areas, going from  electrical and electronic applications (high-frequency capacitors, ferroelectric sensors and actuators, piezoelectric MEMs, magnetic memories, magnetic filters) to energy conversion applications (high-efficiency photovoltaic cells, fuel cells).

This Special Issue is intended to provide the state-of-the-art and new perspectives for several fields of applications of perovskite thin films by collecting papers on the following topics:

  • State-of-the-art and new ideas on the deposition of perovskite thin films;
  • State-of-the-art and developments on perovskite thin film-based systems for electrical applications;
  • State-of-the-art and new perspectives on perovskite thin film-based systems for electronic applications;
  • State-of-the-art and developments on perovskite thin film-based systems for energy conversion applications.

The effects of an applied strain tensor on the electrical resistivity of a manganite granular system are investigated using a simple approach describing the induced deformation in terms of the tilt angle between adjacent grains. The results obtained assuming the resistivity of each grain as given by a metallic part, coming from the inner grain, and a surface-related tunnel contribution, allow us to estimate appreciable resistivity variations even in the case of small deformation angles.

The electronic properties of strontium ruthenate SrRuO3 perovskite oxide thin films are modified by epitaxial strain, as determined by growing on different substrates by pulsed laser deposition. Temperature dependence of the transport properties indicates that tensile strain deformation of the SrRuO3 unit cell reduces the metallicity of the material as well as its metal-insulator-transition (MIT) temperature. On the contrary, the shrinkage of the Ru–O–Ru buckling angle due to compressive strain is counterweighted by the increased overlap of the conduction Ru-4d orbitals with the O-2p ones due to the smaller interatomic distances resulting into an increased MIT temperature, i.e., a more conducting material. In particular, in the more metallic samples, the core level X-ray photoemission spectroscopy lineshapes show the occurrence of an extra-peak at the lower binding energies of the main Ru-3d peak that is attributed to screening, as observed in volume sensitive photoemission of the unstrained material.

Electric noise spectroscopy is a non-destructive and a very sensitive method for studying the dynamic behaviors of the charge carriers and the kinetic processes in several condensed matter systems, with no limitation on operating temperatures. This technique has been extensively used to investigate several perovskite compounds, manganese oxides (La1−xSrxMnO3, La0.7Ba0.3MnO3, and Pr0.7Ca0.3MnO3), and a double perovskite (Sr2FeMoO6), whose properties have recently attracted great attention. In this work are reported the results from a detailed electrical transport and noise characterizations for each of the above cited materials, and they are interpreted in terms of specific physical models, evidencing peculiar properties, such as quantum interference effects and charge density waves.
