{"product_id":"ws-wse-multi-junction-lateral-heterostructure-single-crystals","title":"WS₂\/WSe₂ Multi-junction Lateral Heterostructure Single Crystals","description":"\u003cp dir=\"ltr\"\u003eThe \u003cstrong\u003eWS₂\/WSe₂ multi-junction lateral heterostructure\u003c\/strong\u003e is grown epitaxially by chemical vapor deposition (CVD). Within a single crystal, WS₂ and WSe₂ are grown alternately and periodically along the triangular edges, forming multiple covalently bonded interfaces arranged as concentric nested triangles (a multi-junction structure). Adjacent regions have different band gaps (WS₂ ~2.0 eV, WSe₂ ~1.65 eV), producing a type-II band alignment at each interface and a periodic array of in-plane p–n junctions—an ideal single-crystal platform for studying multi-junction optoelectronic devices, periodic potential engineering, interfacial excitons, and superlattice effects. The crystals exhibit a regular triangular morphology with a single domain, well-defined interfaces, and a clean surface.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e　　\u003cstrong\u003eSample specifications:\u003c\/strong\u003e Grown on a \u003cstrong\u003eSiO₂\/Si\u003c\/strong\u003e substrate (\u003cstrong\u003e2 cm\u003c\/strong\u003e in size), with \u003cstrong\u003ehundreds\u003c\/strong\u003e of crystals per substrate.
