TL;DR: In this article, a metal-doped organic electron injection layer is created by diffusing an ultra-thin layer of about 5-10 Å of a highly electropositive metal such as Li throughout the layer.
Abstract: A highly transparent non-metallic cathode is disclosed that comprises a metal-doped organic electron injection layer that is in direct contact with a transparent non-metallic electron injecting cathode layer, such as indium tin oxide (ITO), wherein the metal-doped organic electron injection layer also functions as an exciton blocking or hole blocking layer. The metal-doped organic electron injection layer is created by diffusing an ultra-thin layer of about 5-10 Å of a highly electropositive metal such as Li throughout the layer. A representative embodiment of the highly transparent non-metallic cathode comprises a layer of ITO, a layer of 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline (BCP), which acts as an electron injection, exciton blocking, and hole blocking layer, and an ultra-thin layer of lithium, which degenerately dopes the layer of BCP, improving the electron injecting properties of the BCP layer. This cathode is demonstrated for use in an OLED having a transparency of about 90% or higher combined with a device external quantum efficiency of about 1% or higher.

TL;DR: Solvent washing and a large-area spray-coating method effectively reduce the wire-wire contact resistances, thus reducing or eliminating the requirement for post-treatment.
Abstract: Silver nanowire (AgNW) random meshes have attracted considerable attention as flexible and high-performance transparent electrodes. Notably, post-treatment of the AgNW random meshes, such as thermal annealing, is usually required to guarantee comparable optical transparency and electrical conductivity to commercial indium tin oxide (ITO). Here, the integral elements of preparing a high-performance, large-area AgNW random mesh network are discussed. High-performance nanostructured transparent electrodes can be obtained without any post-treatment, thereby relieving the restrictions related to the substrate. Solvent washing and a large-area spray-coating method effectively reduce the wire-wire contact resistances, thus reducing or eliminating the requirement for post-treatment.

TL;DR: In this article, the authors used spatially localized sequential infiltration synthesis (SIS) of alumina to increase the plasma etch contrast of polystyrene-block-poly(methyl methacrylate) (PS-b-PMMA) thin films.
Abstract: Block copolymer lithography is a promising approach to massively parallel, high-resolution, and low-cost patterning, but the inherently low etch resistance of polymers has limited its applicability to date. In this work, this challenge is overcome by dramatically increasing the plasma etch contrast of polystyrene-block-poly(methyl methacrylate) (PS-b-PMMA) using spatially localized sequential infiltration synthesis (SIS) of alumina. The PMMA phase of self-assembled PS-b-PMMA block copolymer thin films was selectively infiltrated with alumina yielding an inorganic nanostructure mimicking the original block copolymer template that serves directly as a robust etch mask. SIS-modified films are resistant to a variety of plasma etching chemistries enabling the direct patterning of a range of substrates, including silicon, indium tin oxide, and permalloy, without the need for intermediate hard mask layers. This method considerably simplifies the fabrication of nanostructures in technologically relevant materials...

TL;DR: In this article, a surface-modified Ag anode was proposed for top-emitting organic light emitting devices (OLEDs), which showed device characteristics competitive with those of a bottom-emiting device using the indium tin oxide anode.
Abstract: A high-reflectivity bottom anode is essential for high-performance top-emitting organic light-emitting devices (OLEDs). Ag has the highest reflectivity for visible light among all metals, yet its electronic properties are not ideal for anodes of OLEDs. In this letter, we report that by inducing a thin silver oxide at the surface of Ag, hole injection from Ag anodes into OLEDs is largely enhanced yet with rather high reflectivity retained. Top-emitting devices using such surface-modified Ag anode show device characteristics competitive with those of a bottom-emitting device using the indium tin oxide anode.

TL;DR: In this paper, a simple method was developed to deposit multiple layers of composites consisting of alternating layers of the P2Mo18O626- anion and large, multiply-charged cations such as Os(bpy)32+.
Abstract: The unusually strong, irreversible adsorption of monolayer quantities of the P2Mo18O626- anion on glassy carbon, highly ordered pyrolytic graphite, indium tin oxide, and gold-coated quartz electrodes was examined by electrochemical, spectroelectrochemical, and quartz crystal microgravimetric techniques. A very simple method was developed to deposit multiple layers of composites consisting of alternating layers of the P2Mo18O626- anion and large, multiply-charged cations such as Os(bpy)32+. The resulting deposit is stable and exhibits electroactivity from both of the components that reflects the structure and ionic conductivity of the solid multilayer.
