Sol-gel synthesized indium tin oxide as a transparent conducting oxide with solution-processed black phosphorus for its integration into solar-cells

Description: This article describes the synthesis of indium tin oxide (ITO) thin films using solgel processing with a mixture of InCl₃, methanol, and SnCl₂, where the solutions were spin coated onto glass substrates. The combined architecture of black phosphorus on ITO thin films shows promise in its use for transparent electronics, which can also serve as a stepping stone for future solar cell platforms.

Fabrication of wide-IF 200–300GHz superconductor–insulator–superconductor mixers with suspended metal beam leads formed on silicon-on-insulator

Description: This article reports on a fabrication process that uses silicon-oninsulator (SOI) substrates and micromachining techniques to form wide-IF superconductor–insulator–superconductor (SIS) mixer devices that have suspended metal beam leads for rf grounding. Aside from a description of the fabrication process, electrical measurements of these Nb/Al–AlNₓ /Nb trilayer devices will also be presented.

Fabrication and characterization of inkjet-printed 2D perovskite optoelectronic devices

Description: Article presents the large scale synthesis of solution-processed 2D (CH₃(CH₂)₃NH₃)₂(CH₃NH₃)ₙ − 1PbₙI₃ₙ + 1 (n = 2, 3, and 4) perovskites, a family of layered compounds with composition-tunable bandgap, where inkjet printing was used to fabricate heterostructure, flexible photodetector devices. The flexible, inkjet-printed perovskite 2D heterostructures have significant potential for optoelectronic devices, which can enable broad possibilities with compositional tunability and versatility of the… more

3D-printed and injection molded polymer matrix composites with 2D layered materials

Description: This article reports on a study where 2D TMDs (MoS₂ and WS₂) and the 3D allotrope of carbon and graphite were incorporated into acrylonitrile butadiene styrene (ABS) and polyethylene terephthalate glycol (PETG) matrices in order to form polymer matrix composites (PMCs). The multipronged analysis described in this study was motivated by the purpose to fuse together topics of low-cost, additive manufacturing with 2D layered materials, and studying their ensuing mechanical and tribological propert… more
