Alumini Nitride, O se tasi o mea sili ona folafola sima

2022-10-25

A'o avea ta'amilosaga tu'ufa'atasi ma fa'alapotopotoga fa'apitoa a le atunu'u, o le tele o mea semiconductor na su'esu'eina ma atina'e, ma o le Aluminum Nitride e mautinoa lava o se tasi o mea e sili ona lelei semiconductor.

Alumini Nitride Uiga Fa'atinoga

Aluminum Nitride (AlN) o loʻo i ai uiga o le malosi maualuga, maualuga le voluma resistivity, maualuga insulation voltage, coefficient o le faʻalauteleina o le vevela, fetaui lelei ma le silicon, ma isi. i le fanua o substrates eletise sima ma mea afifiina, lea ua booming i tausaga talu ai nei, ma o lona faatinoga e sili atu nai lo le alumina. Aluminum Nitride ceramics e sili ona lelei le faʻatinoga, e lelei mo semiconductor substrates ma mea faʻapipiʻi faʻapipiʻi, ma e iai le tele o le faʻaogaina i totonu o le pisinisi eletise.

Faʻaaogaina o le Aluminium Nitride

1. Talosaga masini piezoelectric

Aluminum Nitride e maualuga le tetee, maualuga le vevela, ma le maualalo o le faʻalauteleina o le faʻalauteleina e pei o le silicon, o le mea sili lea mo le maualuga o le vevela ma le maualuga o le eletise eletise.

2. mea fa'apipi'i fa'aeletonika

Beryllium Oxide, Alumina, Silicon Nitride, ma Aluminum Nitride o nisi ia o mea masani e faʻaaogaina mo mea faʻapipiʻi sima.

Faatasi ai ma mea faʻapipiʻi o loʻo i ai nei e mafai ona faʻaaogaina e fai ma mea faʻapipiʻi, Silicon Nitride ceramics o loʻo i ai le maualuga o le malosi faʻafefeteina, lelei le faʻaogaina o lavalava, ma mea sili ona lelei faʻainisinia o mea sima, aʻo latou coefficient o le faʻalauteleina o le vevela e sili ona laʻititi. Aluminum Nitride ceramics o loʻo i ai le maualuga o le faʻaogaina o le vevela, lelei le teteʻe o le vevela, ma o loʻo i ai pea mea faʻainisinia lelei i le maualuga o le vevela. E mafai ona fai mai, mai le vaaiga o le faatinoga, Aluminum Nitride ma Silicon Nitride i le taimi nei e sili ona talafeagai mo le faʻaaogaina o mea faʻapipiʻi eletise eletise, ae o loʻo i ai foi se faʻafitauli masani: o latou tau e maualuga.

3. Fa'aaogāga i mea fa'amalama

E tusa ai ma le malosi o le liua o le photoelectric, o le nitride alumini (AlN) o loʻo i ai se fusi faʻapipiʻi faʻapipiʻi saʻo le lautele o le 6.2 eV, lea e maualuga atu nai lo le semiconductor bandgap. AlN, e pei o se mea taua lanumoana ma ultraviolet moli-emitting mea, e faʻaaogaina i le ultraviolet ma loloto ultraviolet light-emitting diodes, ultraviolet laser diodes, ultraviolet detectors, ma isi AlN ma III-group nitrides e pei o GaN ma InN e mafai foi ona fausia ai se faʻaauau pea. fofo, ma le va o le fusi o lona ternary poʻo le quaternary alloy e mafai ona fetuutuunai faʻaauau mai le paʻu vaʻaia i le loloto o le ultraviolet band, ma avea ai ma mea taua e faʻaleleia ai le malamalama.

4. Fa'aoga i mea fa'apipi'i

AlN tioata o le mea sili ona lelei mo GaN, AlGaN, ma AlN epitaxial material. Pe a fa'atusatusa i le safaira po'o le SiC substrates, AlN ma GaN e sili atu le fetaui lelei ma le vaila'au, ma o le mamafa i le va o le substrate ma le epitaxial layer e la'ititi. O le mea lea, o tioata AlN e pei o GaN epitaxial substrates e mafai ona faʻaitiitia ai le tele o le faaletonu i totonu o le masini ma faʻaleleia lona faʻatinoga, lea e iai se faʻamoemoe lelei tele o le faʻaogaina i le sauniuniga o le maualuga o le vevela, maualuga, ma le maualuga o le eletise eletise. E le gata i lea, o le faʻaaogaina o tioata AlN e avea o se mea faʻapipiʻi mea epitaxial AlGaN ma vaega maualuga alumini (Al) e mafai foi ona faʻaitiitia lelei le faʻaletonu i le nitride epitaxial layer ma faʻaleleia atili le faʻatinoga ma le olaga o masini semiconductor nitride. Fa'avae i luga ole AlGaN, ua fa'aogaina lelei le fa'aogaina o se fa'ailoga tauaso maualuga.

5. Fa'aaogāga i sima ma mea e fa'asa'o

Aluminum Nitride e mafai ona faʻaaogaina i le sintering sima fausaga; saunia Aluminum Nitride ceramics e le gata ina sili atu mea faʻainisinia ma flexural malosi nai lo Al2O3 ma BeO ceramics, ae maualuga atu foi maaa ma corrosion resistance.Using le vevela ma le tafia tetee o AlN ceramics, e mafai ona latou faaaogaina e faia crucibles, Al evaporation ipu, ma isi vaega maualuga-vevela corrosion. E le gata i lea, o le AlN ceramics mama mo tioata manino e leai ni lanu, faʻatasi ai ma mea sili ona lelei, e mafai ona faʻaaogaina e avea ma seramics manino mo masini faʻaeletoroni ma masini mo faʻamalama faʻamalama faʻamalama ma faʻasaʻo faʻafefe vevela.
