Ka heke te whai huatanga o ngā pūtau rā ina honoa anō ngā takirua irahiko-pōhatu i mua i te whakamahinga whai hua. Ina mimiti te haurua-ā-ira i te mārama i te roangaru e tika ana, ka puta ngā takirua irahiko-pōhatu. I raro i te whakamārama, ka nui ake te kukū kawe i roto i te rauemi i tōna uara taurite. Kia tangohia te pūtake mārama, ka hoki te kukū kawe ki tōna āhua taurite i roto i tētahi tukanga e kiia nei ko te whakakotahitanga. Kei raro nei ētahi tikanga whakakotahitanga rerekē:
1. Te Whakakotahitanga Irahiko
Ko te whakakotahitanga hihi te ritenga kē o te tukanga mimiti mārama, arā, ka huri te irahiko mai i te āhua pūngao-tiketike ki te āhua pūngao iti iho, ka tukuna te pūngao taikaha hei mārama. He mea nui tēnei momo whakakotahitanga i roto i ngā taiaho haurua-ira me ngā diode tuku mārama (LED) engari kāore i te kaha i roto i ngā pūtau rā silicon.
2. Te Whakakotahitanga o te Auger
Ko te whakakotahitanga o te auger te tukanga whakamuri o te ionization pānga. Ina whakakotahi te irahiko me te pū, ka whakawhitia te kaha taikaha ki tētahi atu irahiko, kaua e tukuna hei māramatanga. Kātahi ka okioki te irahiko whakaohooho ki tōna āhua taketake, ka tukuna ngā phonon (te kaha wiri). Ka tino kitea te whakakotahitanga o te auger i roto i ngā rauemi kua tino tāpirihia, inā koa ka neke ake te kukū poke i te 10¹⁷ cm⁻³, ka waiho hei tukanga whakakotahitanga matua i roto i ēnei take.
3. Te Whakakotahitanga Āwhina-Mahanga
Ka hangaia e ngā poke me ngā hapa i roto i ngā haurua-ā-ira ngā taumata pūngao e whakaaetia ana i roto i te āputa rohe kua rāhuitia. Mā ēnei taumata pūngao hapa ka āwhina i tētahi tukanga whakakotahitanga e rua ngā taahiraa: ka whakangāwari tuatahi te irahiko mai i te roopu arataki ki te taumata hapa, kātahi ki te roopu valence, ka honoa anō ki tētahi kōhao. He tino whai hua tēnei tukanga ki te whakatairanga i te whakakotahitanga, ā, ka pā nui ki te mahi a ngā pūtau rā.
4. Te Whakakotahitanga o te Mata
Ka kitea te mata o te haurua-irahiko hei wāhi e nui ana ngā hapa nā te mutunga o te hanganga tioata. Ka hangaia e ēnei hapa mata he maha ngā āhua pūngao i roto i te āputa rohe kua rāhuitia, ka taea ai te whakakotahi ngāwari. He mea nui te whakakotahitanga mata nā te mea he tino koretake te hanganga tioata i te mata, ka nui ake te tūponotanga ka puta te whakakotahitanga i ēnei rohe.
Whakamutunga
I roto i ngā pūtau rā mahi, ka whai wāhi ēnei tikanga whakakotahitanga ki ngā ngaronga mahi whānui. Ko te mahi a ngā kaihoahoa pūtau he whakaiti i ēnei ngaronga hei whakapai ake i te whai huatanga. He rerekē ngā wero o ia tukanga whakakotahitanga, ā, he mea nui te wikitoria i ēnei mā te whiriwhiri rauemi, te whakakorenga mata, me ngā taumata tāpiringa kua arotauhia hei whakarei ake i te mahi a ngā pūtau rā. Hei tāpiri, ko ngā āhuatanga hoahoa motuhake e wehewehe ana i ngā pūtau rā arumoni rerekē i te mākete, e pā ana ki tō rātou whai huatanga me te pūmanawa tono.
