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. Being single-domain and free of grain boundaries, it serves as an ideal platform for field-effect transistors, photodetectors, and van der Waals heterostructures.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e　　\u003cstrong\u003eSample specifications:\u003c\/strong\u003e Individual triangular crystals measure around \u003cstrong\u003e50 μm\u003c\/strong\u003e; substrates are available in either \u003cstrong\u003esapphire\u003c\/strong\u003e or \u003cstrong\u003eSiO₂\/Si\u003c\/strong\u003e, with a substrate size of \u003cstrong\u003e1.5 cm\u003c\/strong\u003e.
