1. Semiconductors-ka Jiilka Koowaad: Silicon (Si) iyo Germanium (Ge)
Asalka Taariikhiga ah
Sannadkii 1947, Bell Labs waxay ikhtiraacday transistor-ka germanium, taasoo calaamad u ah waagii xilligii semiconductor-ka. Sannadkii 1950-meeyadii, silicon si tartiib tartiib ah ayuu u beddelay germanium isagoo ah aasaaska wareegyada isku dhafan (ICs) sababtoo ah lakabka oksaydhka deggan (SiO₂) iyo keyd dabiici ah oo badan.
Sifooyinka Agabka
ⅠKala-goys:

Taariikhda Horumarinta
Intii u dhaxaysay sanadihii 1970-1980-meeyadii, goobaha soo ifbaxaya sida isgaarsiinta moobaylka, shabakadaha fiilooyinka indhaha, iyo tignoolajiyada dayax-gacmeedka ayaa abuuray baahi degdeg ah oo loo qabo agabyada optoelectronic-ka ee soo noqnoqda oo hufan. Tani waxay horseedday horumarinta semiconductors-ka tooska ah sida GaAs iyo InP.
