United States imapanga zida za semiconductor zokhala ndi matenthedwe apamwamba kwambiri kuti zithetse kutentha kwa chip.
Ndi kuchuluka kwa ma transistors mu chip, magwiridwe antchito apakompyuta akupitilizabe kuyenda bwino, koma kachulukidwe kakang'ono kumatulutsanso malo ambiri otentha.
Popanda teknoloji yoyenera yoyendetsera kutentha, kuwonjezera pa kuchepetsa kuthamanga kwa purosesa ndi kuchepetsa kudalirika, palinso zifukwa zopewera kutenthedwa komanso kumafuna mphamvu zowonjezera, kulenga mavuto osagwira ntchito mphamvu.Kuti athetse vutoli, University of California, Los Angeles idapanga zida zatsopano za semiconductor zokhala ndi matenthedwe apamwamba kwambiri mu 2018, omwe amapangidwa ndi boron arsenide yopanda chilema ndi boron phosphide, yomwe ili yofanana ndi zida zomwe zilipo kale zotaya kutentha monga. diamondi ndi silicon carbide.chiŵerengero, ndi maulendo oposa 3 matenthedwe matenthedwe.
Mu Juni 2021, University of California, Los Angeles, idagwiritsa ntchito zida zatsopano za semiconductor kuphatikiza ndi zida zamakompyuta zamphamvu kwambiri kuti zithetse bwino kutentha kwa tchipisi, potero kuwongolera magwiridwe antchito apakompyuta.Gulu lofufuzira linayika boron arsenide semiconductor pakati pa chip ndi kutentha kwakuya monga kuphatikiza kwa kutentha kwa kutentha ndi chip kuti chiwongolere kutentha kwa kutentha, ndikuchita kafukufuku wokhudzana ndi kayendetsedwe ka kutentha kwa chipangizo chenichenicho.
Pambuyo polumikiza gawo lapansi la boron arsenide ku gawo lalikulu lamphamvu la gallium nitride semiconductor, zidatsimikiziridwa kuti matenthedwe a gallium nitride/boron arsenide mawonekedwe anali okwera kwambiri mpaka 250 MW/m2K, ndipo mawonekedwe amatenthedwe amakafika pamlingo wochepa kwambiri.Boron arsenide gawo lapansi limaphatikizidwanso ndi chipangizo chapamwamba cha electron mobility transistor chip chopangidwa ndi aluminiyamu gallium nitride/gallium nitride, ndipo zimatsimikiziridwa kuti kutentha kwapang'onopang'ono kumakhala bwino kwambiri kuposa diamondi kapena silicon carbide.
Gulu lofufuza linagwiritsira ntchito chip pamlingo waukulu kwambiri, ndikuyesa malo otentha kuchokera kutentha kwa chipinda mpaka kutentha kwambiri.Zotsatira zoyesera zikuwonetsa kuti kutentha kwa sinki ya kutentha kwa diamondi ndi 137 ° C, silicon carbide heat sink ndi 167 ° C, ndipo boron arsenide heat sink ndi 87 ° C kokha.Matenthedwe abwino kwambiri a mawonekedwe awa amachokera ku gulu lapadera la phononic band la boron arsenide ndi kuphatikiza kwa mawonekedwe.Boron arsenide zakuthupi sikuti zimakhala ndi matenthedwe apamwamba kwambiri, komanso zimakhala ndi mawonekedwe ang'onoang'ono kukana kutentha.
Itha kugwiritsidwa ntchito ngati choyatsira kutentha kuti ikwaniritse mphamvu zogwiritsira ntchito zida zapamwamba.Akuyembekezeka kugwiritsidwa ntchito pakulankhulana kwakutali kwakutali, kopanda zingwe mtsogolo.Itha kugwiritsidwa ntchito m'munda wamagetsi amagetsi apamwamba kwambiri kapena ma CD amagetsi.
