He ʻokoʻa loa nā waiwai uila o nā ʻiliʻili lahilahi mai nā mea nui, a he paʻakikī ke loaʻa kekahi mau hopena kino i hōʻike ʻia ma nā ʻiliʻili lahilahi ma nā mea nui.
No nā metala nui, emi iho ke kū'ē ma muli o ka emi ʻana o ka mahana. I nā mahana kiʻekiʻe, emi wale ke kū'ē i hoʻokahi manawa me ka mahana, ʻoiai ma nā mahana haʻahaʻa, emi iho ke kū'ē i ʻelima mau manawa me ka mahana. Eia naʻe, no nā kiʻiʻoniʻoni lahilahi, he ʻokoʻa loa ia. Ma kekahi ʻaoʻao, ʻoi aku ke kiʻekiʻe o ka resistivity o nā kiʻiʻoniʻoni lahilahi ma mua o nā metala nui, a ma kekahi ʻaoʻao, emi wikiwiki ka resistivity o nā kiʻiʻoniʻoni lahilahi ma mua o nā metala nui ma hope o ka emi ʻana o ka mahana. ʻO kēia no ka mea i ke ʻano o nā kiʻiʻoniʻoni lahilahi, ʻoi aku ka nui o ka hāʻawi ʻana o ka hoʻopuehu ʻana o ka ʻili i ke kū'ē.
ʻO kekahi hōʻike ʻē aʻe o ka conductivity o ka ʻili lahilahi maʻamau ʻole ka mana o ke kahua magnetic ma ke kūʻē ʻana o ka ʻili lahilahi. ʻOi aku ka nui o ke kūʻē ʻana o kahi ʻili lahilahi ma lalo o ka hana a kahi kahua magnetic waho ma mua o kahi mea e like me ka poloka. ʻO ke kumu, i ka wā e neʻe ai ka ʻili i mua ma ke ala spiral, inā ʻoi aku ka nui o ka radius o kona laina spiral ma mua o ka mānoanoa o ka ʻili, e hoʻopuehu nā electrons ma ka ʻili i ka wā o ke kaʻina hana neʻe, e hopena ana i kahi kūʻē hou aʻe, kahi e alakaʻi ai i ke kūʻē ʻana o ka ʻili ma mua o ka mea e like me ka poloka. I ka manawa like, e ʻoi aku ka nui ma mua o ke kūʻē ʻana o ka ʻili me ka ʻole o ka hana o kahi kahua magnetic. ʻO kēia hilinaʻi o ke kūʻē ʻana o ka ʻili ma ke kahua magnetic ua kapa ʻia ʻo Magnetoresistance effect, kahi i hoʻohana pinepine ʻia e ana i ka ikaika o ke kahua magnetic. No ka laʻana, ʻo nā cell solar ʻili lahilahi a-Si, CulnSe2, a me CaSe, a me Al203 CeO, CuS, CoO2, CO3O4, CuO, MgF2, SiO, TiO2, ZnS, ZrO, etc.
