Izakhiwo nokusetshenziswa kwamafilimu edayimane isahluko 1

Idayimane elakhiwe ngokuhlanganiswa kwamakhemikhali okuqinile linezakhiwo ezikhethekile zokuwumshini nokunwebeka. Ukuqina, ukuminyana kanye nokushisa kwedayimane kuphakeme kakhulu phakathi kwezinto ezaziwayo. Idayimane futhi linemodulus ephakeme kakhulu yokunwebeka kwanoma iyiphi into. I-coefficient of friction yefilimu yedayimane ingu-0.05 kuphela. Ngaphezu kwalokho, idayimane ine-conductivity ephezulu kakhulu yokushisa, ekhuphuka ngesilinganiso esingaphezu kwesihlanu uma ifilimu yedayimane ilungiswa kusetshenziswa ama-isotopes ahlanzekile e-carbon. Isizathu esiyinhloko sokusebenzisa ama-isotopes ekhabhoni ukulungisa idayimane ukunciphisa ukusakazeka kwe-phonon kwedayimane. Njengezinto eziqinile kakhulu, ifilimu yedayimane iyinto enhle yokugqoka, engagqunywa ebusweni bamathuluzi okusika kanye nesikhunta ukuze kuthuthukiswe kakhulu amandla abo obuso nokwandisa impilo yabo yenkonzo. I-coefficient ephansi yokungqubuzana kanye ne-thermal conductivity ephezulu yamafilimu edayimane ingasetshenziswa kumabheringi anesivinini esikhulu sokundiza kwamagama. I-thermal conductivity ephezulu, i-coefficient ephansi yokungqubuzana kanye nokudluliswa kahle kokukhanya kwefilimu yedayimane nakho kuyenza isetshenziswe kaningi njengezinto ezicitshwayo ezicitshwayo.

(2) Izakhiwo ezishisayo kanye nokusetshenziswa kweDayimane
Kulezi zinsuku, ukushiswa kwefilimu yedayimane yokwenziwa kusondele kakhulu kwedayimane lemvelo. Ngenxa ye-thermal conductivity ephezulu kanye nokumelana nogesi okuphezulu, idayimane lingasetshenziswa njengongqimba oluvikelayo lwe-substrate yesekethe edidiyelwe, kanye nongqimba lwe-thermal conductive insulating lwama-solid-state lasers. Ngaphezu kwalokho, izinga lokushisa eliphezulu ledayimane elishisayo, umthamo omncane wokushisa, ikakhulukazi emazingeni okushisa aphezulu lapho umphumela wokukhipha ukushisa ubalulekile, uyinto enhle kakhulu yokucwilisa ukushisa. Ngokuthuthukiswa kobuchwepheshe bokubekwa kwefilimu elincanyana ledayimane le-thermal conductivity yedayimane, lenze ukusetshenziswa kwedayimane elincanyana lefilimu elishisayo kumalaser anamandla amakhulu, ama-microwave namasekhethi ahlanganisiwe kwaba ngokoqobo.
Kodwa-ke, izakhiwo zamafilimu edayimane okwenziwa zihluka kakhulu ngenxa yezinqubo ezihlukene zokulungiselela. Isibonelo, izakhiwo zokuthutha ezishisayo, ezibonakala ngokuyinhloko umehluko omkhulu e-thermal diffusivity kanye ne-thermal conductivity. Ngaphezu kwalokho, ifilimu yedayimane yokwenziwa ikhombisa i-anisotropy eqinile, futhi ukushintshwa okushisayo kokuqina kwefilimu okufanayo okuhambisana nendawo yefilimu ngokusobala kuncane kunaleyo encike endaweni yefilimu. Lokhu kubangelwa amapharamitha ahlukene okulawula enqubweni yokwenza ifilimu. Kungabonakala ukuthi inqubo yokulungiselela amafilimu amancanyana edayimane idinga ukuthuthukiswa ukuze kwenziwe ukusebenza kwawo okuhle kakhulu kusetshenziswe kabanzi.
