A yau, mun shiga cikin wani nau'i na musamman - Schottky diode, wani nau'i na musamman na karfe da semiconductor tare da kewayon aikace-aikace masu mahimmanci.
Fahimtar Schottky Diode
Sabanin mafi yawan gama-gari pn junction diode, Schottky diode yana samar da mahaɗa tsakanin karfe da semiconductor. Wannan yana haifar da shingen Schottky, yankin da aka taƙaita kwararar lantarki. Lokacin da aka yi amfani da wutar lantarki ta hanyar gaba (tabbatacce a gefen karfe), electrons sun shawo kan shingen kuma halin yanzu yana gudana cikin sauƙi. Koyaya, yin amfani da wutar lantarki na baya yana haifar da shinge mai ƙarfi, hana kwararar halin yanzu.
