TMD g\u00fcne\u015f h\u00fccreleri<\/strong>, y\u00fcksek emilim katsay\u0131lar\u0131 sayesinde olduk\u00e7a verimli olma potansiyeline sahiptir. Ayr\u0131ca, iki boyutlu bir yap\u0131ya sahip olan bu malzeme, esnekli\u011fi ve yar\u0131 \u015feffaf yap\u0131s\u0131yla \u00e7e\u015fitli y\u00fczeylerde kullan\u0131labilir. Bu \u00f6zellikler, TMD g\u00fcne\u015f h\u00fccreleri uzay, giyilebilir teknolojiler ve in\u015faat sekt\u00f6rlerinde devrim yaratabilecek potansiyelini g\u00f6steriyor.<\/p>\n

<\/span> Stanford \u00dcniversitesi ve Imec\u2019in Bel\u00e7ika\u2019daki ara\u015ft\u0131rmac\u0131lar\u0131, wafer \u00f6l\u00e7e\u011finde tungsten diselenid (WSe2<\/strong>) filmler \u00fcretmek i\u00e7in yeni bir TMD \u00fcretim tekni\u011fi geli\u015ftirdi. Bu teknik, malzemenin ta\u015f\u0131y\u0131c\u0131 \u00f6mr\u00fcn\u00fc 144 ns\u2019ye \u00e7\u0131kararak \u00f6nceki TMD filmlerinden 14 kat daha iyi performans <\/strong>sa\u011fl\u0131yor. Ara\u015ft\u0131rmac\u0131lar, 30 nm\u2019den ince bir WSe2 filmi \u00fcretmek i\u00e7in iki selenizasyon y\u00f6ntemi kulland\u0131: kat\u0131 kaynak selenyum (SS-Se) ve hidrojen selenid (H2Se) \u00f6nc\u00fcl\u00fc. Kat\u0131 kaynak selenyum 900 santigrat derece gibi y\u00fcksek s\u0131cakl\u0131klarda i\u015flenirken, H2Se selenizasyonu 650 santigrat derece s\u0131cakl\u0131kta ger\u00e7ekle\u015febiliyor. Bu s\u00fcre\u00e7ler sonucunda elde edilen WSe2 filmi, 1.2 ile 1.3 eV enerji band aral\u0131\u011f\u0131na sahip oluyor ve b\u00f6ylelikle g\u00fcne\u015f h\u00fccresi kullan\u0131m\u0131 i\u00e7in ideal bir hal al\u0131yor. <\/figure>\n
