Iimpawu zombane kunye nokusetyenziswa kweefilimu zedayimani
Idayimani ikwanayo ne-bandwidth engavumelekanga, ukuhamba okuphezulu kokuthwala, ukuqhuba kakuhle kobushushu, izinga eliphezulu lokuhamba kwe-electron, i-dielectric constant encinci, i-voltage ephezulu yokuqhekeka kunye nokuhamba kwe-electron hole, njl. I-voltage yayo yokuqhekeka iphezulu kakhulu kune-Si kunye ne-GaAs, kwaye ukuhamba kwayo kwe-electron kunye ne-hole kungaphezulu kakhulu kune-monocrystalline silicon CA:. Ifilimu yedayimani ingasetyenziswa njengezinto ze-semiconductor zokuqonda i-broadband. Okwangoku iphumelele uphando lwe-side out of diamond ine-silicon (isiphumo semveliso yomzimba kunye nesekethe ye-logic, ezi zixhobo zinokungaphantsi kwe-600 ℃ ngaphantsi komsebenzi oqhelekileyo, kwisixhobo se-semiconductor esishushu kakhulu sinethuba elikhulu lokusetyenziswa. Ngenxa yesithuba esikhulu sebhendi yedayimani, ingasetyenziselwa ukukhupha ukukhanya okuluhlaza okwesibhakabhaka, ukufumanisa ukukhanya kwe-ultraviolet, kunye nezixhobo ezivuzayo eziphantsi.
Iimpawu ze-Optical kunye nokusetyenziswa kweefilimu zeDayimani eziThin
Idayimani ineempawu ezintle kakhulu zokukhanya, ukongeza ekubeni kukho iincopho ezincinci zokufunxa (ezibangelwa kukungcangcazela kwe-phonon) kwi-3 ~ 5μm, ukusuka kwi-outer (225nm) ukuya kwi-far infrared (25μm) uluhlu lonke lweebhendi, idayimani inokudluliselwa okuphezulu, yinto efanelekileyo yefestile ye-laser ye-infrared enamandla aphezulu kunye nee-detectors. Idayimani kwi-infrared band yokukhanya okukhanyayo, okwenza kube yimveliso ye-high-density, i-corrosion-resistant front elayishwe yi-outer optical window ithi izinto ezifanelekileyo, ingasetyenziselwa ukuvalelwa kwe-missile yefestile ye-infrared. Ukongeza, i-refractive index yedayimani iphezulu, ingasetyenziswa njengefilimu yokubonisa ukuncipha kwebhetri yelanga. Ifilimu yedayimani yokungena kwe-radar wave ayilula ukuyijika, olu phawu lungasetyenziswa njenge-radome, i-fly kunye ne-missiles xa kubhabha nge-supersonic, i-head cone radar ayinakumelana nobushushu obuphezulu, kwaye kunzima ukumelana namaconsi emvula akhawulezayo kunye nokugqobhoza kothuli, kunye. Idayimani yenziwe nge-radome, ayipheleli nje ekuchitheni ubushushu ngokukhawuleza, ukumelana nokuguguleka kulungile, kodwa ikwanokusombulula i-radome kwisantya esiphezulu sokubhabha ukuze imelane nengxaki yokudibana kobushushu obuphezulu.
Ezinye iindlela zokusetyenziswa kwefilimu yedayimani
Ifilimu yedayimani ine-high Young's modulus kunye ne-elastic modulus, enceda ukuhanjiswa kwamaza e-acoustic acoustic ngesantya esiphezulu, kwaye luhlobo olutsha lwezinto zokwenza izihluzi zamaza e-acoustic angaphezulu ezibuthathaka kakhulu. Idayimani ine-modulus ephezulu yokuthamba kunye nesantya esiphezulu sokusasazwa kwesandi, kwaye ingasetyenziswa njengesandisi-lizwi esiphakamileyo kwisandi esikumgangatho ophezulu.
Idayimani ine-modulus ephezulu yokuthamba kunye nesantya esiphezulu sokusasazwa kwesandi, ngoko ke ingasetyenziswa njengesixhobo se-membrane yokungcangcazela kwisandi esiphakamileyo esinomgangatho ophezulu.
Ukongeza, idayimani izinzile kakuhle kwiikhemikhali kwaye iyamelana nokugqwala ngenxa yee-asidi ezingayi-oxidizing kumaqondo obushushu ahlukeneyo. Icandelo layo eliphambili, ikhabhoni, yinto engenabungozi, engangcolisiyo engasabelani nomzimba womntu. Ngenxa yokuba idayimani ayisabelani negazi lomntu kunye nezinye iziselo zezicubu, idayimani ikwayinto efanelekileyo yokufakelwa kwe-bio kwi-medical, enokusetyenziswa ukwenza iivalvu zentliziyo ezenziweyo.
