Bilayer WS₂ is an \u003cstrong\u003eindirect-bandgap 2H-phase semiconductor\u003c\/strong\u003e whose interlayer coupling gives rise to distinctive optical and electronic properties—including tunable band structure, spin–valley physics, and pronounced second-harmonic and interlayer-exciton behavior—that are absent in the monolayer. The continuous film offers large area and uniform coverage, facilitating large-scale device-array fabrication and subsequent transfer, making it an ideal material platform for the batch integration of \u003cstrong\u003ewafer-scale field-effect transistors, photodetector arrays, and van der Waals heterostructures\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e　　\u003cstrong\u003eSample specifications:\u003c\/strong\u003e Films are grown on \u003cstrong\u003eSiO₂\/Si\u003c\/strong\u003e substrates with a standard substrate size of \u003cstrong\u003e1.5 cm\u003c\/strong\u003e.
