Iahiko paepae iti: Arotauhia te tipu epitaxial, whakaitihia te iahiko paepae o te diode taiaho, me te whakapai ake i te whai huatanga.
3. Pūoko Whakaahua:
Te tairongo teitei: Mā te tuku mārama teitei me te iti o te mātotoru hapa o te PSS ka pai ake te tairongo me te tere urupare o te taputapu whakaahua.
Urupare whānui mō te hihi: he pai mō te kimi hihi-whakaahua mai i te awhe hihi-ultraviolet ki te awhe e kitea ana.
4. Ngā hikohiko mana:
Ātete ngaohiko teitei: He pai te whakamarumaru teitei me te pumau wera o Sapphire mō ngā taputapu hiko ngaohiko teitei.
Te tuku wera whai hua: Ka whakapai ake te kawe wera teitei i te mahi tuku wera o ngā taputapu hiko, ā, ka roa ake te ora o te ratonga.
5. Ngā taputapu Rf:
Mahi auau teitei: He pai te iti o te mate uruhanga me te pumau wera teitei o te PSS mō ngā taputapu RF auau teitei.
Haruru iti: Mā te papatahi teitei me te iti o te mātotoru hapa ka whakaiti i te haruru o te taputapu me te whakapai ake i te kounga tohu.
6. Ngā Pūoko Koiora:
Te kitea o te tairongo teitei: He pai te tuku māramatanga teitei me te pumau matū o te PSS mō ngā pūoko koiora tairongo teitei.
Te hototahitanga ki te koiora: Nā te hototahitanga ki te koiora o te hapaira he mea pai mō ngā tono hauora me te kimi koiora.
Papa hapaira tauira (PSS) me te rauemi epitaxial GaN:
He tino pai te papa sapphire tauira (PSS) mō te tipu epitaxial GaN (gallium nitride). He tata te pūmau whatunga o te sapphire ki te GaN, ka taea te whakaiti i ngā taupatupatu whatunga me ngā hapa i roto i te tipu epitaxial. Ehara i te mea ka whakapai ake te hanganga micro-nano o te mata PSS i te pai o te tango māramatanga, engari ka whakapai ake hoki i te kounga tioata o te papa epitaxial GaN, ā, ka whakapai ake i te mahi me te pono o te LED.
