در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولEfficient synthesis of plate-like crystalline hydrated tungsten trioxide thin films with highly improved electrochromic performancew
In recent years, nanostructured materials have attracted much attention due to their large surface area and size dependent properties, which offer great advantages in various applications. Tungsten trioxide (WO3), a well-known transition metal oxide, has evoked wide interest owing to its distinctive physical and chemical properties that make it suitable for extensive applications in electrochro...
متن کاملPhotocatalysis and Photoelectrochemical Properties of Tungsten Trioxide Nanostructured Films
Tungsten trioxide (WO₃) possesses a small band gap energy of 2.4-2.8 eV and is responsive to both ultraviolet and visible light irradiation including strong absorption of the solar spectrum and stable physicochemical properties. Thus, controlled growth of one-dimensional (1D) WO₃ nanotubular structures with desired length, diameter, and wall thickness has gained significant interest. In the pre...
متن کاملEfficient synthesis of plate-like crystalline hydrated tungsten trioxide thin films with highly improved electrochromic performance.
Plate-like hydrated tungsten trioxide (3WO(3)·H(2)O) films were grown on a fluorine doped tin oxide (FTO) coated transparent conductive substrate via an efficient, facile and template-free hydrothermal method. The film exhibited a fast coloration/bleaching response (t(c90%) = 4.3 s and t(b90%) = 1.4 s) and a high coloration efficiency (112.7 cm(2) C(-1)), which were probably due to a large surf...
