He aha ke kūpaʻa wela o ke kumu granite i nā lako semiconductor?

He ʻano pōhaku ka Granite i ʻike ʻia no kona paʻakikī, kūpaʻa, a me ke kūʻē ʻana i ka pala kemika. No laila, ua lilo ia i koho kaulana no ke kumu o nā lako semiconductor. ʻO ke kūpaʻa wela o ke kumu granite kekahi o kona mau hiʻohiʻona hoihoi loa.

ʻO ke kūpaʻa wela e pili ana i ka hiki o kahi mea ke kūʻē i nā loli i kona ʻano ke hōʻike ʻia i nā mahana kiʻekiʻe. I loko o ke ʻano o nā lako semiconductor, he mea nui e loaʻa i ke kumu ke kūpaʻa wela kiʻekiʻe no ka mea e hana ana nā lako i nā mahana kiʻekiʻe no nā manawa lōʻihi. Ua ʻike ʻia he kūpaʻa wela maikaʻi loa ko Granite, me kahi coefficient haʻahaʻa o ka hoʻonui wela (CTE).

ʻO ke CTE o kahi mea e pili ana i ka nui o ka loli o kona mau ana ke hōʻike ʻia i nā loli o ka mahana. ʻO ka CTE haʻahaʻa ke ʻano he emi ka hiki ke wili a hoʻololi paha ka mea ke hōʻike ʻia i nā mahana like ʻole. He mea nui loa kēia no ke kumu o nā lako semiconductor, pono e noho paʻa a pālahalaha e hōʻoia i nā hopena pololei a hilinaʻi hoʻi.

Ke hoʻohālikelike ʻia me nā mea ʻē aʻe i hoʻohana pinepine ʻia no nā kumu lako semiconductor, e like me ka alumini a me ke kila kila, ʻoi aku ka haʻahaʻa o ka CTE o ka granite. ʻO ia hoʻi, hiki iā ia ke kū i nā mahana kiʻekiʻe me ka ʻole o ka warping a i ʻole deforming. Eia kekahi, ʻo ka conductivity thermal o ka granite e ʻae iā ia e hoʻokuʻu koke i ka wela, hiki ke kōkua i ka mālama ʻana i kahi mahana paʻa i ka wā e hana ana.

ʻO kekahi pono o ka hoʻohana ʻana i ka granite ma ke ʻano he kumu no nā lako semiconductor ʻo ia kona kūpaʻa ʻana i ka pala kemika. ʻO nā lako i hoʻohana ʻia i ka hana semiconductor e pili pinepine i ka hoʻohana ʻana i nā kemika ʻino, hiki ke pala a hōʻino i ke kumu. ʻO ke kūpaʻa o ka Granite i ka pala kemika ʻo ia hoʻi hiki iā ia ke kū i ka hōʻike ʻana i kēia mau kemika me ka ʻole o ka pala.

I ka hopena, ʻo ke kūpaʻa wela o ka granite kahi hiʻohiʻona koʻikoʻi no ke kumu o nā lako semiconductor. ʻO kona CTE haʻahaʻa, ka conductivity wela kiʻekiʻe, a me ke kū'ē ʻana i ka pala kemika e lilo ia i mea kūpono no kēia kumu. Ma ka hoʻohana ʻana i ka granite ma ke ʻano he kumu, hiki i nā mea hana semiconductor ke hōʻoia i ke kūpaʻa a me ka pololei o kā lākou lako, e hopena ana i nā huahana kiʻekiʻe a me ka hoʻonui ʻana i ka pono.
