Durable, low-cost, printable, large-area, stretchable bright-light-emitting nafion polymer/ 2D molybdenum disulfide semiconductor photonic circuits

"fragility/ low light yield overcome: nafion reinforces fragile 2D layer/ heals surface defects achieving orders magnitude greater light-emitting efficiency... stacked alternating 2D molybdenum sulfide/ nafion layers... preserves the ideal behavior of the 2D layer, even in thick, flexible membranes... no longer fragile material was then deployed in large-area membranes that were markedly brighter and remained stable in air, in water and when stretched... compact, flexible stretchable displays in computer chips/ lasers"
