Izinto ezikhutshwayo emhlabeni molybdenum cathode

Uphawu lwe-athomu ye-membrane ye-cathode ku-adsorb umaleko obhityileyo wesinye isinyithi kumphezulu wesinyithi esinye, esihlawuliswa ngokufanelekileyo kwisiseko sesinyithi. Oku kwenza umaleko ophindwe kabini kunye neentlawulo ezilungileyo ngaphandle, kwaye intsimi yombane yale maleko ephindwe kabini inokukhawulezisa intshukumo yee-electron ngaphakathi kwesiseko sesinyithi ukuya phezulu, ngaloo ndlela inciphisa umsebenzi wokuphunyuka kwe-electron yesiseko sesinyithi kunye nokwandisa amandla ayo okukhutshwa kwe-electron. ngamaxesha amaninzi. Lo mphezulu ubizwa ngokuba ngumphezulu wokuvula. Izinto eziphambili ezisetyenziswa njengeentsimbi ze-matrixi-tungsten, molybdenum, kwayenickel.

Indlela yokwakheka komhlaba osebenzayo ngokuqhelekileyo ngumgubo wesinyithi. Yongeza inani elithile le-oxide yenye isinyithi ene-electronegativity ephantsi kunesiseko sesinyithi kwisiseko sesinyithi, kwaye uyenze ibe yi-cathode ngenkqubo ethile yokucubungula. Xa le cathode ishushu phantsi kwe-vacuum kunye nokushisa okuphezulu, i-oxide yensimbi iyancitshiswa ngesiseko sesinyithi ukuze ibe yintsimbi. Kwangaxeshanye, iiathom zentsimbi ezicuthiweyo kumphezulu ezincitshiswe ngokukhawuleza ziphuphuma kubushushu obuphezulu, ngelixa ii-athom zentsimbi ezisebenzayo ngaphakathi ziqhubeka zisasazeka kumphezulu ngemida yeenkozo zesiseko sesinyithi ukongeza.
