control of the optical properties of nanoparticles by laser fields
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 اولEnhancement of epitaxial lateral overgrowth by vapor-phase diffusion
The mathematical model for vapor-phase diffusion-assisted epitaxial lateral overgrowth in homoepitaxy of a compound semiconductor (GaAs-type) thin film is presented. Besides diffusion in vapor phase, the physical mechanisms contributing to the crystal growth and accounted for in the model include surface diffusion and evaporation–recondensation. The evolution equations for the concentrations of...
متن کاملA model for anisotropic epitaxial lateral overgrowth
The model for anisotropic crystal growth on a substrate covered by a mask material with a periodic series of parallel long trenches where the substrate is exposed to the vapor phase is developed. The model assumes that surface diffusion and deposition flux are the main mechanisms of the growth, and that the three key surface quantities (energy, mobility and adatom diffusivity) are anisotropic w...
متن کاملEpitaxial lateral overgrowth of GaN over AlOx surface formed on Si substrate
An approach by which single crystal a-GaN can be grown laterally over oxidized AlAs (AlOx) formed on Si substrates is demonstrated. Regular a-Ga2-O3 stripe templates, spatially separated by AlOx , on which subsequent GaN growth is selectively seeded are formed. Since the boundary between the stripe template and AlOx is nominally planar, two pyramidal planes on separated GaN can merge by growing...

In the original HTML version of this Article, all instances of the orientation [1-10] and [3-11] were incorrectly written as “1,2,3,4,5,6,7,8,9,10” and “3,4,5,6,7,8,9,10,11” respectively. In the original PDF version of this Article, all instances of the orientation [1-10] and [3-11] were given as “1-10” and “3-11” respectively. These errors have now been fixed in the HTML and PDF versions of th...
