Nhanganyaya Inopindira Indery of Aluminium Nitride

Aluminium Nitride ( Aln) ane hunhu hwesimba rakakwirira, rakanyanya kuvhiringidza kupokana, uye kufananidza neiyo silicon, etc. Mumunda weCeramic substrate, ceramic pepa uye marongero emidziyo yakave nemoto mumakore apfuura, uye kuita kwayo kure kupfuura iyo yeAlumina.

Pakati pezvakakosha zvivakwa zvealuminium nitride, zvakanyanya kukosha ndiwo mubatsiri anodzora. Nezve iyo inodonhedza maitiro ealuminium niti Metainiki ndiyo: Vibration kuburikidza neLattice, ndiko kuti, kutamiswa kwekupisa nerubatsiro rwevavhi veLatice kana mafungu ekupisa. Mhedzisiro yehuwandu hwehuwandu huchiudza kuti mafungu eLattice anogona kuongororwa sekufamba kwechikamu, phononi. Mafungu ekupisawo ane wave-turness duality. Kupisa-kutakura mafoni anotambanudza kupisa kuburikidza nehure ririniki uye akarongeka vibrations pakati pemarangi emhando (maatomu, kana mamorekuru, kana mamorekuru). Kana iyo Crystal iri intelastomer yakaringana chimiro, kupisa kunogona kuendeswa pachena kune kutonhora kwechiitiko nekupera kwekristaro pasina kupindira uye kupararira, uye kufambidzana kwesitiri kunogona kusvika pakukosha kwakanyanya. Maitiro ayo anodzidzisa anonyanya kudzorwa nekristaro kuremara uye phonon kupaza nemifananidzo yacho pachavo.

Zvezvinoshorwa, kufambidzana kweAln kunogona kusvika 320- 1 · k-· k-1, asi kuremara uye kuremara muAln, vafambi vearumini . Izvi zvinonyanya kukonzerwa nenyaya yekuti zvikamu zvekumusoro mukati mekristaro hazvigone kugoverwa kwakasimba kweruzhinji, uye panogara matunhu akasiyana uye saka ma pharoni okutakura nguva dzose anogara achivhiringidzwa uye akapararira panguva yekuparadzira.
