Ummangaliso kwicandelo lezixhobo ezisebenzayo
Njengeidayimaniukusetyenziswa kwayo, kubandakanya uluhlu olubanzi lwetekhnoloji kwaye kunzima kakhulu. Ifuna uphando olusebenzisanayo kwiinkalo ezahlukeneyo ukuze luphunyezwe ngexesha elifutshane. Kwixesha elizayo, kuyimfuneko ukuphuhlisa nokuphucula itekhnoloji yokukhula kwedayimani ye-CVD rhoqo kunye nokuhlola ukusetyenziswa kwayo.Idayimani yeCVDifilimu kwi-acoustics, i-optics, kunye nombane. Iya kuba yinto entsha yophuhliso lobuchwepheshe obuphezulu kwinkulungwane yama-21. Ukusetyenziswa kwe-CVD kungasetyenziselwa zombini izixhobo zobunjineli kunye nezixhobo ezisebenzayo. Oku kulandelayo kukwazisa nje ngezicelo zayo ezisebenzayo.
Yintoni into esebenzayo? Izinto ezisebenzayo zibhekisa kwizinto ezahlukeneyo ezinemisebenzi ebonakalayo neyekhemikhali efana nokukhanya, umbane, imagnetism, isandi, kunye nobushushu obusetyenziswa kushishino nakwitekhnoloji, kubandakanya izinto zokusebenza zombane, izinto zokusebenza zemagnethi, izinto zokusebenza ezibonakalayo, izinto zokuqhuba i-superconducting, izinto ze-biomedical, ii-membrane ezisebenzayo, njl.njl.
Yintoni i-membrane esebenzayo? Zithini iimpawu zayo? I-membrane esebenzayo ibhekisa kwi-film material encinci eneempawu ezibonakalayo ezifana nokukhanya, i-magnetism, i-electric filtration, i-adsorption, kunye neempawu zeekhemikhali ezifana ne-catalysis kunye ne-reaction.
Iimpawu zezinto zefilimu ebhityileyo: Izinto zefilimu ebhityileyo zizinto eziqhelekileyo ezinemilinganiselo emibini, oko kukuthi, zinkulu kwizikali ezimbini kwaye zincinci kwisikali sesithathu. Xa kuthelekiswa nezinto ezisetyenziswa rhoqo ezinemilinganiselo emithathu, ineempawu ezininzi ekusebenzeni nakwisakhiwo. Eyona nto iphambili kukuba ezinye iimpawu zeefilimu ezisebenzayo zinokufezekiswa ngeendlela ezikhethekileyo zokulungiselela ifilimu ebhityileyo ngexesha lokulungiselela. Yingakho izinto ezisebenzayo zefilimu ebhityileyo ziye zaba ngumxholo oshushu wokuqwalaselwa nophando.
Njengeizinto ezinamacala amabini, uphawu olubaluleke kakhulu lwezinto zefilimu ebhityileyo luphawu olubizwa ngokuba lobungakanani, olunokusetyenziselwa ukwenza izinto zibe ncinci kwaye ludibanise izinto ezahlukeneyo. Ukusetyenziswa okuninzi kwezinto zefilimu ebhityileyo kusekelwe kweli nqaku, elona liqhelekileyo lisetyenziswa kwiisekethe ezidibeneyo kunye nokwandisa uxinano lokugcina izinto zekhompyutha.
Ngenxa yobukhulu bayo obuncinci, umlinganiselo womphezulu kunye nojongano lwezinto ezikwifilimu encinci mkhulu kakhulu, kwaye iimpawu eziboniswa ngumphezulu zibonakala kakhulu. Kukho uthotho lweziphumo zomzimba ezinxulumene nojongano lomphezulu:
(1) Ukudluliselwa okukhethiweyo kunye nokubonakaliswa okubangelwa sisiphumo sokuphazamiseka kokukhanya;
(2) Ukusasazeka kwe-inelastic okubangelwa kukungqubana kwee-electron nomphezulu kubangela utshintsho kwi-conductivity, i-Hall coefficient, i-current magnetic field effect, njl.njl.;
(3) Ngenxa yokuba ubukhulu befilimu buncinci kakhulu kunendlela ephakathi ekhululekileyo yee-elektroni kwaye ikufutshane nobude be-wavelength ye-Drobyi yee-elektroni, ii-elektroni ezihamba zibuyela umva phakathi kwemiphezulu emibini yefilimu ziya kuphazamisa, kwaye amandla anxulumene nentshukumo ethe nkqo yomphezulu aya kuthatha amaxabiso ahlukeneyo, nto leyo eya kuchaphazela ukuthuthwa kwee-elektroni;
(4) Phezulu, ii-athomu ziyaphazamiseka rhoqo, kwaye inqanaba lamandla omphezulu kunye nenani leemeko zomphezulu eziveliswayo zilingana nobukhulu benani lee-athomu zomphezulu, nto leyo eya kuba nefuthe elikhulu kwizinto ezineenkampani ezimbalwa ezifana nee-semiconductors;
(5) Inani leeathom ezikufutshane zeeathom zemagnethi ezikumphezulu liyancipha, nto leyo ebangela ukuba umzuzu wemagnethi weeathom ezikumphezulu unyuke;
(6) I-Anisotropy yezinto ezibhityileyo zefilimu, njl.njl.
Ekubeni ukusebenza kwezinto zefilimu encinci kuchatshazelwa yinkqubo yokulungiselela, uninzi lwazo lukwimeko yokungalingani ngexesha lenkqubo yokulungiselela. Ke ngoko, ukwakheka kunye nolwakhiwo lwezinto zefilimu encinci kunokutshintshwa kuluhlu olubanzi ngaphandle kokuthintelwa yimeko yokulingana. Ke ngoko, abantu banokulungisa izinto ezininzi ezinzima ukuzifezekisa ngezinto ezininzi kwaye bafumane iipropati ezintsha. Olu luphawu olubalulekileyo lwezinto zefilimu encinci kwaye sisizathu esibalulekileyo sokuba izinto zefilimu encinci zitsale ingqalelo yabantu. Nokuba kusetyenziswa iindlela zekhemikhali okanye zomzimba, ifilimu encinci eyilwe ngendlela ethile inokufumaneka.
