Solution-Based Fabrication of Polycrystalline Si Thin-Film Transistors from Recycled Polysilanes

Currently, research has been focusing on printing and laser crystallization of cyclosilanes, bringing to life polycrystalline silicon (poly-Si) thin-film transistors (TFTs) with outstanding properties. However, the synthesis of these Sibased inks is generally complex and expensive. Here, we prove that a polysilane ink, obtained as a byproduct of...
