Ka hangaia e te United States nga rauemi semiconductor me te kaha o te wera wera hei pehi i te whakamahana maramara.
Na te piki haere o te maha o nga transistors i roto i te maramara, kei te pai haere tonu te mahi rorohiko o te rorohiko, engari ko te nui o te densification he maha nga waahi wera.
Ki te kore e tika te hangarau whakahaere waiariki, i tua atu i te whakaheke i te tere o te mahi o te tukatuka me te whakaheke i te pono, he take ano mo te Aukati i te wera me te hiahia atu i te kaha, te hanga i nga raruraru koretake o te kaha.Hei whakatau i tenei raru, i whakawhanakehia e te Whare Wananga o California, Los Angeles tetahi rauemi semiconductor hou me te tino kaha o te kawe werawera i te tau 2018, he mea kohakore te boron arsenide me te boron phosphide, he rite ki nga taonga tohanga wera o mua penei i te taimana me te carbide silicon.ōwehenga, me te neke atu i te 3 whakareatanga o te werawera.
I te Pipiri 2021, i whakamahia e te Whare Wananga o California, Los Angeles, nga rauemi semiconductor hou ki te whakakotahi me nga maramara rorohiko kaha-kaha ki te peehi angitu i te whakangao wera o nga maramara, na reira ka pai ake te mahi rorohiko.I whakauruhia e te roopu rangahau te boron arsenide semiconductor i waenga i te maramara me te totohu wera hei whakakotahitanga o te totohu wera me te maramara hei whakapai ake i te paanga o te wera, me te whakahaere rangahau mo nga mahi whakahaere waiariki o te taputapu tuuturu.
I muri i te hono i te tïpako arsenide boron ki te whänui aputa püngao gallium nitride semiconductor, i whakapümauhia ko te kawe i te waiariki o te atanga gallium nitride/boron arsenide he teitei ki te 250 MW/m2K, me te atanga waiariki i tae ki te taumata iti rawa.Ko te tïpako arsenide boron ka honoa atu ki te maramara whakawhiti hiko hiko teitei teitei i tito mai i te konumohe gallium nitride/gallium nitride, a ka whakapumautia he tino pai ake te paanga o te wera i tera o te taimana me te carbide silicon.
I whakahaerehia e te roopu rangahau te maramara i te kaha teitei, me te ine i te waahi wera mai i te pāmahana rūma ki te teitei teitei.Ko nga hua whakamatautau e whakaatu ana he 137°C te paemahana o te totohu wera taimana, he 167°C te totohu wera o te carbide silicon, me te 87°C anake te totohu wera o te boron arsenide.Ko te pai o te kawe waiariki o tenei atanga ka ahu mai i te hanganga roopu phononic ahurei o te boron arsenide me te whakaurunga o te atanga.Ko te rauemi arsenide boron ehara i te mea he nui te kawe waiariki, engari he iti te atanga atanga waiariki.
Ka taea te whakamahi hei totohu wera hei whakatutuki i te mana whakahaere o te taputapu teitei ake.Ko te whakaaro ka whakamahia i roto i nga korero ahokore tawhiti-tawhiti, kaha-nui a muri ake nei.Ka taea te whakamahi i roto i te waahi o te hikohiko hiko teitei o te hikohiko hiko ranei.
