{"product_id":"btb050501us","title":"Bi2Te3 Highly Oriented Crystal Substrate (001) irregular shape(about 5x5x0.1 mm) as Cleaved - BT-050501","description":"\u003cp\u003eBismuth telluride crystal substrate is highly oriented crystal ( not  single crystal ), which is a narrow gap layered semiconductor with a hexagonal structure.  The valence and conduction band structure can be described as a many-ellipsoidal model with 6 constant-energy ellipsoids that are centered on the reflection planes. General thermoelectric materials, thermoelectric factor is currently the largest pure-phase block; mechanical dissociation can get high-quality topological insulator material.\u003cbr\u003e\u003c\/p\u003e\n\u003cdiv\u003e\u003cstrong\u003e\u003cspan\u003eSpecifications:\u003c\/span\u003e\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eStructure:                      Hexagonal, group 166R-3M\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eGrown method:              High-pressure vertical Bridgman\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eLattice constant:           a=4.38A    c=30.5A\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSubstrate orientation:    highly oriented layer structure along \u0026lt;0001\u0026gt;\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSurface:                        as Cleaved\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003ePurity:                             99.999%, atomic ratio,\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan face=\"Arial\"\u003e\u003cspan\u003eMeltingPoint               585 oC\u003c\/span\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eResistivity :                  0.1-5 mohm. cm\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan lang=\"EN\"\u003eMobility\u003c\/span\u003e\u003cspan lang=\"EN\"\u003e\u003cspan\u003e \u003c\/span\u003e:                     3000 cm2 \/ V.s \u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan lang=\"EN\"\u003eGeneral\u003c\/span\u003e\u003cspan lang=\"EN\"\u003e\u003cspan\u003e \u003c\/span\u003eSize:               irregular shape,about 5 mm x 5 mm x 0.1mm\u003c\/span\u003e\u003cspan\u003e,\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003ePacking:                      packed in plastic bag with vacuum\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"MTI","offers":[{"title":"Default Title","offer_id":44984910708875,"sku":"BTb050501US","price":0.0,"currency_code":"MYR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/4405\/3643\/files\/1.3.png?v=1764851896","url":"https:\/\/mtimalaysia.com\/products\/btb050501us","provider":"MTI Malaysia \u0026 Indonesia","version":"1.0","type":"link"}
