Abstract
The possibility of producing stable thin films, only a few atomic layers thick, from a variety of materials beyond graphene has led to two-dimensional (2D) materials being studied intensively in recent years. By reducing the layer thickness and approaching the crystallographic monolayer limit, a variety of unexpected and technologically relevant property phenomena were observed, which also depend on the subsequent arrangement and possible combination of individual layers to form heterostructures. These properties can be specifically used for the development of multifunctional devices, meeting the requirements of the advancing miniaturization of modern manufacturing technologies and the associated need to stabilize physical states even below critical layer thicknesses of conventional materials in the fields of electronics, magnetism and energy conversion. Differences in the structure of potential two-dimensional materials result in decisive influences on possible growth methods and possibilities for subsequent transfer of the thin films. In this review, we focus on recent advances in the rapidly growing field of two-dimensional materials, highlighting those with oxidic crystal structure like perovskites, garnets and spinels. In addition to a selection of well-established growth techniques and approaches for thin film transfer, we evaluate in detail their application potential as free-standing monolayers, bilayers and multilayers in a wide range of advanced technological applications. Finally, we provide suggestions for future developments of this promising research field in consideration of current challenges regarding scalability and structural stability of ultra-thin films.
Highlights
Crystalline thin-films of complex oxide materials possess a wide range of fascinating physical, electronic, chemical and optical 2D correlated properties which can be tuned due to their stoichiometry- or composition-dependency and deviate entirely from the behaviour of the bulk solid due to the reduction of dimensions and symmetry [1,2,3]
Thin films are often characterized by high electron mobility, high thermal conductivity and optical transparency due to strong inplane covalent bonds and atomic layer thickness [22,23,24,25]
Useful interface functions can be further boosted by stacking layers of unus2uoafl31material combinations to create heterostructures that allow the targeted adjustment of electronic properties, strongly modify the optical properties [35] and evoke exotic quantum phenoUmseefnual [i2n0te]r. face functions can be further boosted by stacking layers of unusual material Icnom20b1in7a,tTioanns etot carle.,ahteyhpeottehroesstirzuecdtutrheastt,hwatitahllothwethheeltparogfetseuditaadbjulestemxepnetriomf eelnetcatrlocnoicnditipornosp,etrhteieps,rsotdrouncgtilyonmoofdaifnyythfoeromptoicfatlwporo-dpiemrtieenss[i3o5n]aalnmdaetveorkiaelsexisotpicoqssuiabnletu, mpropvhiedneodmt-hat theeniar [g2r0o]w. th can be restricted to two dimensions and a few atomic layers [2]
