An updated state-of-the art in complex oxide science

Oxide thin films and related interfaces display a plethora of functionalities and emerging properties that call for a pivotal role in electronics beyond Moore’s dictate.

''Towards Oxide Electronics: a Roadmap", elaborated within the framework of the TO-BE COST Action, addresses crucial questions related to development and implementation of these materials in emerging technologies. Namely: What is the future role of oxide thin film in modern technologies? How far are oxides from taking this role? Which are the competing technologies? Which are the hurdles presently preventing the diffusion of marketable applications? Which are the chances these hurdles can be overcome? Which are the advancement in synthesis and characterization methods that can help us facing them?

We focused explicitly on thin-film-based applications, and when possible on epitaxial films. Most of the applications presented are expected to impact the fields of ICT and Energy. In times in which mankind is facing the extreme ambition of artificially emulating the computing power of a human brain, exceeding the exaFLOP range and corresponding, with the present energy-hungry electronic technologies, to a power consumption in the several GW range, the two fields are related as never before. Selected topics of this Roadmap include: (a) Insights from theory and modelling, (b) advanced growth, nanofabrication and characterization techniques and (c) applications on: data storage and computing, optics and plasmonics, magnonics, energy conversion and harvesting, and power electronics. This Roadmap is a valuable tool as a collective self-analysis of the oxide electronics community, providing an updated picture of the state-of-the-art in the field, and as a dissemination tool, helpful to whoever is willing to spread knowledge about oxide science and to attract towards this exciting field of research new young scientists and further public and private resources.

The paper contains 28 contributions by about 56 authors and its elaboration has been chaired by Mariona Coll and Josep Fontcuberta from ICMAB, together with Fabio Miletto Granozio and Nini Pryds.
