2.Ibipimo byerekana ubushyuhe
o Ubushyuhe bw'itanura rya Vacuum: 600-650 ° C.
o Komeza igihe gishyushye: amasaha 4-6
Ifu ya Zinc selenide ifite ubunini bwa 2-10 μm ikorwa na fonction fonction reaction 4.
Kugereranya inzira zingenzi
| buryo | Ibicuruzwa byerekana imiterere | Ingano ya Particle/ubunini | Crystallinity | Imirima yo gusaba |
| Uburyo bwa solvothermal 35 | Nanoballs / inkoni | 20-100 nm | Cubic sphalerite | Ibikoresho bya Optoelectronic |
| Umwuka wumwuka 6 | Inzitizi za polycrystalline | 60-100 mm | Imiterere ya mpande esheshatu | Amashanyarazi |
| Uburyo bukomeye icyiciro 4 | Ifu nini ya Micron | 2-10 mm | Icyiciro cya Cubic | Ibikoresho bitagira ingano |
Ingingo z'ingenzi zigenga uburyo bwihariye bwo kugenzura: uburyo bwa solvothermal bukeneye kongeramo surfactants nka acide oleic kugirango igenzure morphologie 5, kandi imyuka iva mubyuka isaba ububobere bwa substrate kuba
1. Kubika imyuka yumubiri (PVD).
1.Inzira y'Ikoranabuhanga
o Ibikoresho bya Zinc selenide bihumeka mu kirere kandi bigashyirwa hejuru yubutaka hakoreshejwe ikoranabuhanga ryuka cyangwa ubushyuhe bwumuriro12.
o Inkomoko yo guhumeka ya zinc na seleniyumu yashyutswe ku bipimo bitandukanye by'ubushyuhe (zone ya zinc: 800-850 ° C, agace ka seleniyumu: 450-500 ° C), kandi igipimo cya stoichiometric kigenzurwa no kugenzura igipimo cyuka.12。
2.Kugenzura ibipimo
o Icyuho: ≤1 × 10⁻³ Pa
o Ubushyuhe bwibanze: 200-400 ° C.
o Igipimo cyo kubitsa:0.2–1.0 nm / s
Filime ya Zinc selenide ifite uburebure bwa 50-500 nm irashobora gutegurwa gukoreshwa muri infragre optique 25.
