A zazzabi dakin (300k), numfashin zafi zai yi wasu makamashi na waje suna samun isasshen kuzari don rabuwa da wutan hadari kuma ku zama masu ɗaukar ciki na kyauta, ana kiran wannan tsari na kyauta. Bayan Elllon ba shi da tabbas ne don zama mai lantarki kyauta, an bar wani wuri a cikin hadari. Ana kiran wannan wuri. Bayyanar rami muhimmin fasali ne wanda ke bambanta semiconducorctor daga shugaba.

A lokacin da karamin adadin ƙimar ƙwararrun ƙwararren irinsu kamar phosphorus an ƙara zuwa ga smicononducor na ciki, zai sami ƙarin clecron bayan samar da ciyawar da atom. Wannan karin lantarki kawai yana buƙatar ƙaramin ƙarfi don kawar da bond kuma ya zama mai lantarki kyauta. Wannan nau'in tsarkakakken tsinkaye shine ake kira semicononductor (n-rubuta semiconductor). Koyaya, ƙara karamin adadin muhimmi mai tasiri (kamar boron, da sauransu) zuwa ga semicarctor atoms, zai haifar da gurbata wuri guda uku, zai haifar da gurbata wuri a cikin kristal.
