Zinc Realrude (ZNTE), II II-VI Semiconductor Chinyorwa, inoshandiswa zvakanyanya mukuonekwa, maseru ezuva, uye zvishandiso zveSoltolectronic. Dzazvino kufambira mberi muNanootechnology uye Green Chemistry vakagadzirira kugadzirwa kwaro. Pazasi ndidzo dziripo riripo zte maitiro ekugadzira maitiro uye kiyi paramita, kusanganisira nzira dzechinyakare uye dzidziso dzemazuva ano:

I. Yetsika yekugadzira maitiro (Direct synthesis)
1. Kugadzirira kwezvinhu
• Yakakwira-yakanyanya zinc (zn) uye kutaurisa (te): kuchenesa ≥99.999% (5n giredhi), yakasanganiswa mu1: 1 molar ratio.
• Inodzivirira gasi: yakakwirira-yekuchenera Argon (ar) kana nitrogen (n₂) kudzivirira oxidation.
2. Maitiro anoyerera
• nhanho 1: vacuum melting synthesis
O Sunga zn uye te pody mune quartz tube uye kubuda kuna ≤10⁻³ PA.
o Kuparadza Chirongwa: Kupisa pa5-10 ° C / Min kusvika 500-700 ° C, bata kwemaawa 4-6.
o Reaction equation: ZN + Te → δzntezn + teşzte
• nhanho yechipiri: inosimbisa
o AnNeal chigadzirwa chisina kuchena pa400-500 ° C kweawa 2-3 kuti uderedze lattice urema.
• nhanho 3: kupwanya uye kusvetuka
o Shandisa bhora chigayo kuti ugone kugaya zvinhu zvehuwandu kune chinangwa chevhu chevhu (yakakwira-simba bhora balling yeNanoscale).
3. Kiyi parameter
• Tembiricha yekudzora kurongeka: ± 5 ° C
• Kutonhora Kuroora: 2-5 ° C / Min (Kuti udzivise kupaza kushushikana kwemarara)
• Raw zvinyorwa zvevhu saizi: ZN (100-200 mesh), te (200-300 mesh)

Ii. Maitiro emazuva ano Akavandudzwa (Solvothothomal Nzira)
Iyo nzira yekuSolothothothomal ndiyo nzira huru yekugadzira Nanoscale Zte, inopa zvakanakira zviyero zvakadai seyakagadziriswa chikamu uye yakaderera simba rekushandisa.
1. Zvishandiso zvakagadzirwa uye solvent
• Precursors: Zinc Nitrate (zn (no₃) ₂) uye sodium taudium
• Kuderedza vamiririri: Hydrazine hydrate (n₂h₄ · h₂o) kana sodium borohydride (NABH₄).
• Sol Solventts: Etlelediamine (ADA) kana Dioned Mvura (di mvura).
2. Maitiro anoyerera
• Nhanho 1: Precursor Dissolution
o Dissolve Zn (no₃) ₂ uye nave ye 1: 1 molar ratio muSolvent pasi kumutsa.
• nhanho 2: kuderedza kuita
o Wedzera iyo yekuderedza mumiririri (semuenzaniso, n₂h₄₄ · h₂o) uye chisimbiso mune yakakwirira-kumanikidza autoclave.
o Kuita mamiriro ezvinhu:
Kupisa: 180-220 ° C
Nguva: 12-24 maawa
Dzvinyiriro: Kuzvigadzira (3-5 MPA)
o Reaction equation: Zn2 ++ Teo32- + kuderedza Mumiriri → ZNTE + BYPTHING
• nhanho 3: post-kurapwa
o Centrifuge kuti zviparadzanise chigadzirwa, geza ka3-5 times ne ethanol uye di mvura.
o yakaoma pasi pecuum (60-80 ° C kwemaawa 4-6).
3. Kiyi parameter
• Precursor Concentration: 0.-0.5 Mol / L
• PH Control: 9-11 (Alkaline Mamiriro Ekufarira Reaction)
• Chikamu chekureka kudzora: gadzirisa kuburikidza solvent mhando (semuenzaniso, eda inopa nanowi;

III. Mamwe maitiro epamberi
1. CHEMICAL ACHEMON DOPINY (CVD)
• Chishandiso: kugadzirira-firimu kugadzirira (semuenzaniso, maseru ezuva).
• Precursors: Diethylzinc (zn (c₂h₅) ₂) uye difethyltelluramu (te (c₂h₅) ₂).
• Paramita:
o Kuisa tembiricha: 350-450 ° C
o Kutakura Gasi: H₂ / Ar musanganiswa (kuyerera chiyero: 50-100 sccm)
o Dzvinyiriro: 10⁻²-10⁻³ Torr
2. Mechancal Allying (bhora yekugaya)
• Zvimiro: solvent-yemahara, yakaderera-tembiricha synthesis.
• Paramita:
o bhora-to-poda ratio: 10: 1
o Kugaya Nguva: 20-40 maawa
o Kutenderera kumhanya: 300-500 rpm

Vi. Maitiro ehunyanzvi
• Green synthesis: Gadzira masisitimu emvura kuti adzore organic solvent kushandiswa.
• Doping Kugadziridzwa: Kusimbisa Kufambidzana naDoping neCu, AG, nezvimwe.
• Yakakura-chiyero kugadzirwa: Tora kuenderera-kuyerera-kuyerera kunoyerera kugadzirisa kg-zviyero mabheti.
