• Khase e sireletsang: Bohareng ba Argon (ar) kapa naetrojene (N₂) ho thibela oxida.
2. Ts'ebetso phallo
• Mohato oa 1: vacuum e qhibilihang Syntthesis
O kopanya zn le tewdder ka thapo ea Quark'hupelo le evacuate ho ≤10⁻³ Pa.
Lenaneo la ho futhumatsa: mocheso ka 5-10 ° C / min ho 500-700 ° C, tšoara lihora tse 4-6.
Otunce Equation: Zn + Te → δ δ δztezn + terollazte
• Mohato oa Bobeli: Khana
O Abisa sehlahisoa se sa tsotelleng ka 400-500 ° C bakeng sa lihora tse 2-3 ho fokotsa likokoana-hloko.
• Mohato 3: Ho sithabetsa le ho hlapaola
Sebelisa Mill Mill ho grand ea bongata ho mofuta oa karohano ea lintho tse thata
3. Litekanyetso tsa sehlooho
• Ho nepahala ha mocheso: ± 5 ° C
• Litemana tse futhumatsang: 2-5 ° C / Min (ho qoba khatello ea maikutlo ea li-armal)
• Boholo ba lintho tse tala: ZN (100-200 mesh), Te (200-300 mesh)

II. Ts'ebetso ea sejoale-joale e ntlafalitsoeng (mokhoa oa Solvelolmal)
Mokhoa oa Solvelolmal ke mokhoa oa mantlha oa ho hlahisa Zontecale Znte ea Nanoscale Znte e kang boholo bo laoloang le matla a tlase.
1. Lisebelisoa tse tala le li-solven
• Precorsors: Zinc nitrate (zn (no₃) ₂) le sodium Burumite (Nahateo₃) kapa.
• Lisebelisoa tsa ho fokotsa: Hydrazine Hydrate (NLH₄ · HYDRAZINE (NNAH₄ · HUNDAO) Kapa NOHH₄O) kapa Sodium Borohydride (Nabh₄).
• solvels
2. Ts'ebetso phallo
• Mohato oa 1: Disooltion disfort
O Dissolve ZN (no₃) ₂ le Nauteo₃ ho 1: 1 palesa ea lar ea solvent tlasa ho hlohlelletsa.
• Mohato oa Bobeli: Phokotso ea Phokotso
Kenya moemeli oa ho fokotsa litheko (mohlala, n₂h₄ · bonaclao) le tiiso ka autoclave e phahameng.
O Maemo a Liketso:
Mocheso: 180-220 ° C
Nako ea "lihora tse 12-24
Khatello: Ho hlahisoa (3-5 mpa)
o Tabatabelo ea maikutlo: Zn2 ++ Teo32- +
• Mohato oa 3: Ka mor'a kalafo
O Ho ikarola ho khetholla sehlahisoa, ho hlatsoa makhetlo a 3-5 le Ethanol le Kotsi.
o omme ka tlas'a vacuum (60-80 ° C bakeng sa lihora tse 4-6).
3. Litekanyetso tsa sehlooho
• Contacont Constrant: 0.1-0.5 MOEL / L
• Taolo ea PH: Maemo a 9-11 (Maemo a Alkaline a ratang)
• Taolo ea boholo ba li-vuntig

III. Mehato e meng e tsoetseng pele
1. Chemical vapor deposition (CVD)
• Kopo: Litokiso tse nyefolang tsa lifilimi (mohlala, lisele tsa letsatsi).
• Precorsors: Dibolonylzinc (ZN (C₂h₅) ₂) le Dithyltelurium (Te (C₂h₅).
• Paramenter:
o Mocheso oa Deposition: 350-450 ° C
O Khase ea Carrier: H₂ / Motsoako oa AR (Tekanyetso ea Flow
O Khatello: 10⁻²-10⁻ Catr
2. Mochini o sa sebetseng oa (milling ea bolo)
• Litšobotsi: Synthais-mahala, ea mocheso o tlase.
• Paramenter:
o karolela-papali ea bolo ea maoto: 10: 1
ka nako ea milling ea milling: lihora tse 20-40
Lebelo la ho potoloha: 300-500 rpm
