It is a \u003c\/span\u003e\u003cstrong\u003enarrow-bandgap semiconductor\u003c\/strong\u003e\u003cspan\u003e with strong in-plane anisotropy in its electrical, optical, and thermoelectric properties. The non-centrosymmetric puckered lattice hosts in-plane ferroelectricity and pronounced piezoelectric and nonlinear optical responses, making GeSe an important earth-abundant, non-toxic candidate for \u003c\/span\u003e\u003cstrong\u003eanisotropic optoelectronics, photovoltaics, and two-dimensional ferroelectrics\u003c\/strong\u003e\u003cspan\u003e.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eGrowth method: Chemical vapor transport (CVT).\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eSample specifications: Individual crystals measure approximately 5 mm, with a purity of up to 99.9999% (6N), and multiple high-quality single-crystal pieces included in each package.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eExfoliation: Difficult — strong interlayer bonding; mechanical exfoliation typically yields thick flakes, and ultrathin flakes are challenging to isolate.\u003c\/span\u003e\u003c\/p\u003e","brand":"2D Material Supermarket","offers":[{"title":"Default Title","offer_id":53906207080632,"sku":"2MS-GeSe","price":4088.0,"currency_code":"CNY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0649\/0069\/4200\/files\/7ada38403c813852262a1642dce11320.png?v=1786623928","url":"https:\/\/2dmaterialsupermarket.com\/products\/gese-germanium-selenide","provider":"2D Material Supermarket","version":"1.0","type":"link"}
