Ngā Whakatairanga i roto i te Mārama ki ngā Āhuatanga Rauemi mā roto i ngā Huarahi Whakamātautau me ngā Huarahi Ariā

**Taitara: Ngā Whakatairanga i roto i te Mārama ki ngā Āhuatanga Rauemi mā roto i ngā Huarahi Whakamātautau me ngā Huarahi Ariā**

I roto i tētahi rangahau hou i whakaputaina tata nei, kua angitu ngā kairangahau ki te whakakotahi i ngā tikanga whakamātautau me ngā tikanga ariā kia hohonu ake ai te māramatanga ki ngā āhuatanga o ngā rauemi matatau. Ehara i te mea ka whakarei ake tēnei huarahi auaha i tō tātou māramatanga ki te whanonga o ngā rauemi anake, engari ka whakatakoto hoki i te ara mō te whanaketanga o ngā tono hou i roto i ngā momo mara, tae atu ki te hikohiko, te rokiroki pūngao, me te nanotechnology.

I tīmata te rōpū rangahau, he hunga ahupūngao, he kaimātai matū, me ngā kaipūtaiao rauemi, i tēnei kaupapa me te whāinga kia wetewetehia ngā taunekeneke uaua e whakahaere ana i ngā āhuatanga rauemi i ngā taumata ngota me ngā taumata ngota. Mā te whakauru i ngā raraunga whakamātautau ki ngā tauira ariā, i whai ngā kairangahau ki te waihanga i tētahi anga whānui e taea ai te matapae i te whanonga o ngā rauemi i raro i ngā āhuatanga rerekē.

Ko tētahi o ngā kaupapa matua o te rangahau ko te rangahau i tētahi momo rauemi hou e mōhiotia ana ko ngā rauemi rua-ahu (2D). Kua aro nuitia ēnei rauemi, tae atu ki te graphene me ngā dichalcogenides whakarewa whakawhiti, nā ō rātou āhuatanga hiko, whatu, me te miihini ahurei. Heoi, he uaua tonu te mārama ki ngā tikanga matua e whai wāhi ana ki ēnei āhuatanga.

Hei whakatika i tēnei, i whakamahia e ngā kairangahau he huinga o ngā tikanga whakamātautau matatau, pērā i te karuārai kaha atomika (AFM) me te karuārai Raman, me ngā tikanga tātai pērā i te ariā mahi kiato (DFT). Nā tēnei huarahi takirua i taea ai e rātou te tirotiro i ngā whanonga o ngā rauemi i te wā tūturu, me te whakamana anō hoki i ā rātou matapae ariā.

I roto i te wāhanga whakamātautau i hangaia he tauira kounga teitei o ngā rauemi 2D, ā, i tukuna atu ki ngā momo whakaohooho o waho, pērā i ngā huringa pāmahana me te ahotea miihini. I tuhia marietia e te tīma ngā urupare a ngā rauemi, ā, i whakaratohia he raraunga whai hua hei whakapai ake i ā rātou tauira ariā.

I te taha ariā, i whakawhanakehia e ngā kairangahau ngā whakatauira matatau e whakaatu ana i ngā taunekeneke i waenga i ngā ngota me te awe o ngā āhuatanga o waho. Mā te whakataurite i ngā hua mai i ā rātou whakatauira ki ngā raraunga whakamātautau, i taea e rātou te tautuhi i ngā rerekētanga me te whakapai ake i ā rātou tauira. Kāore i te whakapai ake noa i te tika o ā rātou matapae tēnei tukanga auau, engari i whakahōhonu ake anō hoki i tō rātou māramatanga ki ngā mātāpono matua e whakahaere ana i te whanonga rauemi.

Ko tētahi o ngā kitenga nui o te rangahau ko te kitenga o tētahi whakawhiti āhua kāore i te mōhiotia i mua i roto i tētahi o ngā rauemi 2D. Ko tēnei whakawhiti āhua, e puta ana i raro i ngā āhuatanga motuhake, ka tino whakarerekē i ngā āhuatanga hiko o te rauemi. E whakapono ana ngā kairangahau ka taea e tēnei kitenga te arahi ki te whanaketanga o ngā taputapu hiko hou e whakamahi ana i ēnei āhuatanga ahurei hei whakapai ake i te mahi.

Heoi anō, nā te huarahi tahi i āhei ai te tīma ki te tūhura i te pūmanawa o ēnei rauemi i roto i ngā tono rokiroki pūngao. Mā te mārama ki te taunekeneke a ngā rauemi me ngā iona i te wā e utu ana, e tuku ana hoki i te hiko, ka taea e ngā kairangahau te whakaaro i ngā whakarerekētanga hei whakapai ake i te whai huatanga me te kaha o ngā pākahiko me ngā supercapacitors.

Ko ngā pānga o tēnei rangahau kei tua atu i ngā kitenga o nāianei. Ko te whakaurunga angitu o ngā tikanga whakamātautau me ngā tikanga ariā he tauira mō ngā rangahau ā muri ake nei i roto i te pūtaiao rauemi. Mā te whakatairanga i te mahi tahi i waenga i ngā kaiwhakamātautau me ngā kaitātari ariā, ka taea e ngā kairangahau te whakateretere i te kitenga o ngā rauemi hou me te arotau i ō rātou āhuatanga mō ngā tono motuhake.

Haunga āna takoha pūtaiao, e whakaatu ana te rangahau i te hiranga o te mahi tahi a ngā momo mātauranga ki te aro atu ki ngā wero uaua o te pūtaiao rauemi. I whakanuia e ngā kairangahau he mea nui te mahi tahi i waenga i ngā momo mara mātauranga hei akiaki i te auahatanga me te whakatairanga i te hangarau.

I te mea kei te piki haere tonu te hiahia mō ngā rauemi matatau, inā koa i roto i te horopaki o ngā otinga pūngao tauwhiro me ngā hikohiko o te whakatupuranga e whai ake nei, ka tino whai hua ngā māramatanga i riro mai i tēnei rangahau. Mā te kaha ki te matapae tika i te whanonga o ngā rauemi ka taea e ngā kaihangarau me ngā kaihoahoa te waihanga i ngā hua whai hua me te whai hua, ā, i te mutunga ka whai hua te hapori whānui.

Hei whakamutunga, ko te huarahi whakamātautau me te huarahi ariā e whakamahia ana i roto i tēnei rangahau he taahiraa nui ki mua i roto i tō tātou māramatanga ki ngā āhuatanga o ngā rauemi. Mā te hono i te āputa i waenga i te ariā me te mahi, ehara i te mea kei te hurahia e ngā kairangahau ngā āhuatanga hou anake, engari kei te whakatakoto hoki i te turanga mō ngā whanaketanga ā muri ake nei i roto i te pūtaiao rauemi. I te haere tonu o te whanaketanga o tēnei mara, kei te nui tonu te kaha mō ngā tono me ngā hangarau auaha, e oati ana i tētahi heke mai kanapa ake, pumau ake hoki.
