Dokar Wiedemann-Franz ta bayyana cewa mafi kyawun halayen lantarki na kayan, mafi kyawun yanayin zafi.Koyaya, kayan vanadium dioxide keɓantacce ne, wanda baya bin wannan doka.

Masu binciken sun kara wani siriri na vanadium dioxide, wani fili da ke canzawa daga na'urar insulator zuwa na'urar da ke kusa da 68 ° C, zuwa gefe daya na gilashin.Vanadium dioxide (VO2)abu ne mai aiki tare da kaddarorin mika mulki na thermal na yau da kullun.Za a iya canza yanayin halittarsa ​​tsakanin insulator da karfe.Yana aiki azaman insulator a cikin ɗaki da zafin jiki kuma azaman mai sarrafa ƙarfe a yanayin zafi sama da 68°C.Wannan shi ne saboda gaskiyar cewa tsarinsa na atomic yana iya canzawa daga tsarin yanayin zafin jiki zuwa tsarin karfe a yanayin zafi sama da 68 ° C, kuma canjin yana faruwa a kasa da 1 nanosecond, wanda shine fa'ida ga aikace-aikacen lantarki.Binciken da ya danganci ya sa mutane da yawa suyi imani cewa vanadium dioxide na iya zama kayan juyin juya hali don masana'antun lantarki na gaba.

Masu bincike a jami'ar Switzerland sun ƙara yawan zafin canjin lokaci na vanadium dioxide zuwa sama da 100 ° C ta hanyar ƙara germanium, wani abu mai ƙarancin ƙarfe, zuwa fim ɗin vanadium dioxide.Sun yi nasara a aikace-aikacen RF, ta yin amfani da vanadium dioxide da fasahar canza canjin lokaci don ƙirƙirar matattarar mitar mai ƙarfi, mai sauƙin daidaitawa a karon farko.Wannan sabon nau'in tacewa ya dace musamman ga mitar da tsarin sadarwar sararin samaniya ke amfani da shi.

Bugu da ƙari, abubuwan da ke cikin jiki na vanadium dioxide, irin su resistivity da infrared transmittance, za su canza sosai a lokacin tsarin canji.Duk da haka, yawancin aikace-aikacen VO2 suna buƙatar zafin jiki ya kasance kusa da zafin jiki, kamar: windows masu kyau, masu gano infrared, da dai sauransu, da kuma doping na iya rage yawan zafin jiki na lokaci.Doping tungsten element a cikin VO2 fim na iya rage yanayin canjin yanayin fim ɗin zuwa kusa da zafin jiki, don haka tungsten-doped VO2 yana da fa'idodin aikace-aikace.

Injiniyoyi na Hongwu Nano sun gano cewa za a iya daidaita yanayin canjin lokaci na vanadium dioxide ta hanyar doping, damuwa, girman hatsi, da dai sauransu. Abubuwan da ake amfani da su na iya zama tungsten, tantalum, niobium da germanium.Tungsten doping ana ɗaukarsa a matsayin mafi inganci hanyar doping kuma ana amfani dashi sosai don daidaita yanayin canjin lokaci.Doping 1% tungsten na iya rage yanayin canjin lokaci na fina-finan vanadium dioxide da 24 ° C.

Ƙayyadaddun ƙayyadaddun lokaci na nano-vanadium dioxide da tungsten-doped vanadium dioxide wanda kamfaninmu zai iya samarwa daga hannun jari sune kamar haka:

1. Nano vanadium dioxide foda, undoped, m lokaci, lokaci mika mulki zafin jiki ne 68 ℃

2. Vanadium dioxide doped tare da 1% tungsten (W1% -VO2), da lokaci mika mulki zafin jiki ne 43 ℃

3. Vanadium dioxide doped tare da 1.5% tungsten (W1.5% -VO2), lokaci mika mulki zafin jiki ne 32 ℃

4. Vanadium dioxide doped tare da 2% tungsten (W2% -VO2), da lokaci mika mulki zafin jiki ne 25 ℃

5. Vanadium dioxide doped tare da 2% tungsten (W2% -VO2), da lokaci mika mulki zafin jiki ne 20 ℃

Ana sa ran nan gaba, waɗannan tagogi masu kaifin baki tare da tungsten-doped vanadium dioxide za a iya shigar da su a duk faɗin duniya kuma suna aiki a duk shekara.
