Iintsimbi ezininzi kunye neekhompawundi zazo kufuneka zenziwe zibe ziifilim ezibhityileyo phambi kokuba zisetyenziswe kwiimveliso zobugcisa ezifana ne-electronics, iziboniso, iiseli zepetroli, okanye ii-catalytic applications.Noko ke, iintsimbi “ezikwaziyo ukuxhathisa,” kuquka iplatinum, iridium, ruthenium, netungsten, kunzima ukuzijika zibe ziifilimu ezicekethekileyo kuba amaqondo obushushu aphakamileyo (ngokuqhelekileyo angaphezu kwama-2 000 ngokukaCelsius) kufuneka ajike abe ngumphunga.
Ngokuqhelekileyo, izazinzulu zidibanisa ezi filim zentsimbi zisebenzisa iindlela ezinje nge-sputtering kunye ne-electron beam emvaporation.Le yokugqibela ibandakanya ukunyibilika kunye nokuphuma kwesinyithi kwiqondo lokushisa eliphezulu kunye nokubunjwa kwefilimu encinci phezu kweplate.Nangona kunjalo, le ndlela yesiko iyabiza, idla amandla amaninzi, kwaye isenokungakhuselekanga ngenxa yombane ophezulu osetyenziswayo.
Ezi zinyithi zisetyenziselwa ukwenza iimveliso ezingenakubalwa, ukusuka kwii-semiconductors kwizicelo zekhompyuter ukubonisa ubugcisa.Ngokomzekelo, iPlatinam nayo iyinto ebalulekileyo yokuguqula amandla kunye ne-catalyst yokugcina kwaye ithathelwa ingqalelo ukusetyenziswa kwizixhobo ze-spintronics.
