{"product_id":"polar-crystals-von-yuriy-poplavko","title":"Polar Crystals","description":"\u003cp\u003eA novel conception of piezoelectricity physical nature is proposed and dicussed. Some peculiarities of piezoelectric crystals (so cold polar-neutral crystals) would be described by a assumption of their intrinsic (latent) polarity. Its components show a critical law P ~ (¿ ¿ T)^n and vanish at the phase transition temperature ¿. The critical parameter equals to n = 1 if all components of intrinsic polarity are flatness arranged (two-dimen- sional case, 2D). For spatial (3D) arrangement of the latent polarity components this exponent is n = 2. These differ essentially from 1D ferroelectric spontaneous polarization that shows P(T) critical law with the n = 0.5. For technical application, it means that under the anisotropy of boundary conditions any high-gap III-V semiconductor-piezoelectric shows a behavior of pyroelectric crystal. Such crystals might be used as far infrared sensor or as a piezoelectric sensor integrated with amplifier in one III-V crystal.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659542909\"\u003e\u003ch3\u003ePhysical Nature and New Effects\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783659542909","offer_id":39467343904861,"sku":"9783659542909","price":32.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/6a4b12e8-f966-4440-8af3-4420c7befb0b.jpg?v=1773554758","url":"https:\/\/shop.autorenwelt.de\/products\/polar-crystals-von-yuriy-poplavko","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
