Theem hloov kub ntawmtungsten-doped vanadium dioxide(W-VO2) feem ntau yog nyob ntawm cov ntsiab lus tungsten. Qhov tshwj xeeb theem hloov pauv kub yuav txawv nyob ntawm qhov kev sim thiab cov khoom sib xyaw alloy. Feem ntau, raws li cov ntsiab lus tungsten nce, theem hloov pauv kub ntawm vanadium dioxide txo qis.

HONGWU muab ob peb qhov sib xyaw ntawm W-VO2 thiab lawv cov kev hloov pauv theem kub:

Ntshiab VO2: theem hloov pauv kub yog 68 ° C.

1% W-doped VO2: theem hloov pauv kub yog 43 ° C.

1.5% W-doped VO2: theem hloov pauv kub yog 30 ° C.

2% W-doped VO2: theem hloov pauv kub ntawm 20 txog 25 ° C.

Kev siv ntawm tungsten-doped vanadium dioxide:

1. Temperature sensors: Tungsten doping tso cai rau kev hloov pauv theem ntawm qhov kub thiab txias ntawm vanadium dioxide, ua kom nws nthuav dav hlau-insulator hloov pauv nyob ze ntawm chav tsev kub. Qhov no ua rau tungsten-doped VO2 haum rau qhov ntsuas kub ntsuas los saib xyuas qhov kub thiab txias hloov hauv qhov kub thiab txias.

2. Cov ntaub thaiv npog thiab cov iav ntse: Tungsten-doped VO2 tuaj yeem siv los tsim kho cov ntaub thaiv npog thiab cov iav ntse nrog lub teeb xa hluav taws xob tswj tau. Nyob rau hauv qhov kub thiab txias, cov khoom muaj ib tug metallic theem nrog high light absorption thiab tsis tshua muaj transmittance, thaum nyob rau hauv tsis tshua muaj kub, nws muaj ib tug insulating theem nrog high transmittance thiab tsis muaj teeb pom kev zoo. Los ntawm kev kho qhov kub thiab txias, kev tswj xyuas meej ntawm lub teeb xa hluav taws xob tuaj yeem ua tiav.

3. Optical keyboards thiab modulators: Cov hlau-insulator hloov pauv tus cwj pwm ntawm tungsten-doped vanadium dioxide tuaj yeem siv rau cov hloov kho qhov muag thiab cov hloov kho. Los ntawm kev kho qhov kub thiab txias, lub teeb tuaj yeem tso cai rau hla los yog thaiv, ua kom lub teeb liab hloov pauv thiab hloov kho.

4. Cov khoom siv thermoelectric: Tungsten doping ua rau kev hloov pauv ntawm ob qho tib si hluav taws xob conductivity thiab thermal conductivity ntawm vanadium dioxide, ua rau nws tsim nyog rau kev hloov pauv thermoelectric. Tungsten-doped VO2 tuaj yeem siv los tsim cov khoom siv hluav taws xob ua haujlwm siab rau lub zog sau thiab hloov pauv.

5. Ultrafast optical li: Tungsten-doped vanadium dioxide qhia ultrafast optical teb thaum lub sij hawm hloov txoj kev. Qhov no ua rau nws tsim nyog rau kev tsim cov khoom siv kho qhov muag ultrafast, xws li ultrafast optical keyboards thiab laser modulators.
