ʻOkoʻa loa nā waiwai uila o nā kiʻiʻoniʻoni lahilahi mai nā mea waiwai nui, a paʻakikī kekahi mau hopena kino i hōʻike ʻia ma nā kiʻi ʻoniʻoni lahilahi.
No nā metala nui, emi ke kū'ē ma muli o ka emi ʻana o ka mahana. Ma nā wela kiʻekiʻe, hoʻemi ke kū'ē i hoʻokahi wale nō me ka mahana, akā ma nā haʻahaʻa haʻahaʻa, emi ke kū'ē iʻelima manawa me ka mahana. Eia naʻe, no nā kiʻi ʻoniʻoni lahilahi, ʻokoʻa loa ia. Ma kekahi ʻaoʻao, ʻoi aku ka kiʻekiʻe o ka resistivity o nā kiʻiʻoniʻoni lahilahi ma mua o nā metala nui, a ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka wikiwiki o ka resistivity o nā kiʻi ʻoniʻoni lahilahi ma mua o nā metala nui ma hope o ka emi ʻana o ka mahana. ʻO kēia no ka mea ma ke ʻano o nā kiʻiʻoniʻoni lahilahi, ʻoi aku ka nui o ka hāʻawi ʻana o ka hoʻopuehu ʻana i ka ʻili i ke kūʻē.
ʻO kekahi hōʻike ʻē aʻe o ka conductivity kiʻiʻoniʻoni lahilahi maʻamau ka hopena o ke kahua magnetic ma ke kūpaʻa kiʻiʻoniʻoni lahilahi. ʻOi aku ka ʻoi aku o ke kūʻē ʻana o kahi kiʻiʻoniʻoni lahilahi ma lalo o ka hana ʻana o kahi māla magnetic waho ma mua o ka mea like me ka poloka. ʻO ke kumu ke neʻe nei ke kiʻiʻoniʻoni i mua ma ka trajectory spiral, ʻoiai ʻoi aku ka lōʻihi o ka radius o kāna laina spiral ma mua o ka mānoanoa o ke kiʻiʻoniʻoni, e hoʻopuehu ʻia nā electrons i ka ʻili i ka wā o ka neʻe ʻana, e hopena i kahi kūʻē hou, e alakaʻi ana i ke kūʻē ʻana o ke kiʻi i ʻoi aku ka nui ma mua o ka mea like me ka poloka. I ka manawa like, e ʻoi aku ka nui ma mua o ke kū'ē ʻana o ke kiʻiʻoniʻoni me ka ʻole o ka hana o kahi kahua magnetic. Ua kapa ʻia kēia hilinaʻi ʻana o ke kūpaʻa kiʻiʻoniʻoni ma ke kahua magnetic, ka hopena Magnetoresistance, ka mea maʻamau i hoʻohana ʻia e ana i ka ikaika o ke kahua magnetic. No ka laʻana, a-Si, CulnSe2, a me CaSe kiʻiʻoniʻoni ʻoniʻoni solar, a me Al203 CeO, CuS, CoO2, CO3O4, CuO, MgF2, SiO, TiO2, ZnS, ZrO, etc.
