Stoichiometric oxide perovskites have the generic formula AMO3 in which the A site is at the center of a simple cubic array of M sites; the oxide ions form (180 ° 4)) M O M bridges to give an MO3 array of corner shared MO6\/2 octahedra and the larger A cations have twelvefold oxygen coordination. Mismatch between the A O and M O equilibrium bond lengths introduces internal stresses. A compressive stress on the MO3 array is accommodated by a lowering of the M O M bond angle from 180 ° to (180 ° 4)); a tensile stress on the M O M bonds is accommodated by the formation of hexagonal polytypes [4].\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783540675228\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783642086960\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Hardcover - 9783540675228","offer_id":50696662150,"sku":"9783540675228","price":320.99,"currency_code":"EUR","in_stock":true},{"title":"Softcover - 9783642086960","offer_id":39429881036893,"sku":"9783642086960","price":320.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/016f8ae4-671c-4f15-8347-0a5133a6589c.jpg?v=1778819173","url":"https:\/\/shop.autorenwelt.de\/en\/products\/localized-to-itinerant-electronic-transition-in-perovskite-oxides-von-john-b-goodenough-hrsg","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
