Book Description
This book provides a modern introduction to the growth, characterization, and physics of iron-based superconducting thin films. Iron pnictide and iron chalcogenide compounds have become intensively studied key materials in condensed matter physics due to their potential for high temperature superconductivity. With maximum critical temperatures of around 60 K, the new superconductors rank first after the celebrated cuprates, and the latest announcements on ultrathin films promise even more. Thin film synthesis of these superconductors began in 2008 immediately after their discovery, and this growing research area has seen remarkable progress up to the present day, especially with regard to the iron chalcogenides FeSe and FeSe1-xTex, the iron pnictide BaFe2-xCoxAs2 and iron-oxyarsenides. This essential volume provides comprehensive, state-of-the-art coverage of iron-based superconducting thin films in topical chapters with detailed information on thin film synthesis and growth, analytical film characterization, interfaces, and various aspects on physics and materials properties. Current efforts towards technological applications and functional films are outlined and discussed. The development and latest results for monolayer FeSe films are also presented. This book serves as a key reference for students, lecturers, industry engineers, and academic researchers who would like to gain an overview of this complex and growing research area.

Book Description
Among the newly discovered iron-based superconductor, FeSe with the simplest structure and a transition temperature (T_c) around 8 K arouses much research interest. Although its Tc is much lower than that of the cuprates, iron chalcogenide has low anisotropy, slow decrease of the critical current density (J_c) with increasing magnetic field and high upper critical field H_c2 as well as easy composition control, which makes it a promising candidate to substitute NbSn/NbTi for high field applications. Compared with its bulk counterpart, iron-based superconductor thin film has a great potential in developing the ordered quasi-2D structure and is suitable for coating technology which has already been applied in YBa_2Cu_3O_7-x coated conductors. In this thesis, we first optimized pure FeSe thin films by different growth conditions using pulsed laser deposition (PLD) and post-annealing procedures. The microstructure properties of the films including the epitaxial quality, interface structure and secondary phase have been studied and correlated with the superconducting properties. Second, we reported our initial attempt on introducing the flux pinning centers into FeSe_0.5Te_0.5 thin films either under a controlled oxygen atmosphere or with a thin CeO_2 interlayer. The microstructure of the FeSe_0.5Te_0.5 films including the epitaxial quality, the interface structure and the secondary phase have been studied and correlated with the in-field performance of the superconducting thin films to explore the pinning properties of these nanoscale defects. Very recently, ion beam assisted deposition (IBAD) substrates have been used to grow high quality FeSe_0.5Te_0.5 tape with excellent in-field performance. The film on IBAD substrate involves multiple steps of seed layer and buffer layer deposition to establish the epitaxial growth template. Therefore a simplified and cost effective iron-based coated conductor is more desirable. Towards the practical application, we demonstrated the growth of superconducting FeSe_0.5Te_0.5 film on amorphous glass substrates for the first time. The film is highly textured with excellent superconducting properties, e.g., T_c of 10 K and J_c under self-field as high as 1.2 x 10^4 A/cm^2 at 4 K. Further optimization of the film growth with various nanoscale interlayers has been carried out. In addition the Te rich iron chalcogenide thin film with composition close to the composition with antiferromagnetic (AFM) transition has been demonstrated. Compared to the FeSe_0.5Te_0.5 which claimed to be the optimum composition from the literature report, the FeSe_0.1Te_0.9 is even more promising for the high field application with its coexistence of super high upper critical field and high critical current density.

Book Description
This volume presents an in-depth review of experimental and theoretical studies on the newly discovered Fe-based superconductors. Following the Introduction, which places iron-based superconductors in the context of other unconventional superconductors, the book is divided into three sections covering sample growth, experimental characterization, and theoretical understanding. To understand the complex structure-property relationships of these materials, results from a wide range of experimental techniques and theoretical approaches are described that probe the electronic and magnetic properties and offer insight into either itinerant or localized electronic states. The extensive reference lists provide a bridge to further reading. Iron-Based Superconductivity is essential reading for advanced undergraduate and graduate students as well as researchers active in the fields of condensed matter physics and materials science in general, particularly those with an interest in correlated metals, frustrated spin systems, superconductivity, and competing orders.

Book Description
Superconductivity often emerges on the border of a broken-symmetry phase in iron-based high-temperature superconductors. Previous bulk studies have shown that the broken symmetry phase is suppressed by chemical doping or pressure in a parent material and the superconducting transition temperature is highest for regular tetrahedral geometry. However, little is known about how to deliberately maintain a regular tetrahedron through a tetragonal-to-orthorhombic phase transition. I present an epitaxial thin films approach for the atomic structure design of iron-based superconductors to understand the relation between structure and properties, and enhance the superconducting transition temperature (Tc). Epitaxial thin film heterostructures and superlattices lead to the study of interface engineering and strain engineering for manipulating atomic configurations at the interface. Furthermore, the suppression of an orthorhombic phase transition by dimension control is suggested, which enables atomic geometry to a reach regular tetrahedron with two independent structural parameters such as tetragonality and orthorhombicity. Finally, I will describe the influence of atomic geometry on Tc, which potentially reveals an intriguing interplay between magnetism and superconductivity.

Book Description
Thin films have an extremely broad range of applications from electronics and optics to new materials and devices. Collaborative and multidisciplinary efforts from physicists, materials scientists, engineers and others have established and advanced a field with key pillars constituting (i) the synthesis and processing of thin films, (ii) the understanding of physical properties in relation to the nanometer scale, (iii) the design and fabrication of nano-devices or devices with thin film materials as building blocks, and (iv) the design and construction of novel tools for characterization of thin films.Against the backdrop of the increasingly interdisciplinary field, this book sets off to inform the basics of thin film physics and thin film devices. Readers are systematically introduced to the synthesis, processing and application of thin films; they will also study the formation of thin films, their structure and defects, and their various properties — mechanical, electrical, semiconducting, magnetic, and superconducting. With a primary focus on inorganic thin film materials, the book also ventures on organic materials such as self-assembled monolayers and Langmuir-Blodgett films.This book will be effective as a teaching or reference material in the various disciplines, ranging from Materials Science and Engineering, Electronic Science and Engineering, Electronic Materials and Components, Semiconductor Physics and Devices, to Applied Physics and more. The original Chinese publication has been instrumental in this purpose across many Chinese universities and colleges.
