主　　题：transparent neglected enable 

摘      要：The long-standing challenge in designing far-infrared transparent conductors(FIRTC)is the combination of high plasma absorption edge(λ_(p))and high conductivity(σ).These competing requirements are commonly met by tuning carrier concentration or/and effective carrier mass in a metal oxide/oxonate with low optical dielectric constant(ε_(opt)=2-7).However,despite the highσ,the transparent band is limited to mid-infrared(λ_(p)15 andλ_(p)15μ*** FIRTC crystals are mainly octahedrally-coordinated heavy-metal chalcogenides and their solid solutions with shallow-level *** highε_(opt)relies on the formation of electron-deficiency multicenter bonds resulting in the great electron-polarization *** new FIRTC enables us to develop the first“continuous filmtype far-infrared electromagnetic shielder that is unattainable using traditional ***,this study may inaugurate a new era in far-infrared optoelectronics.
