چکیده مقاله:

در این مقاله تأثیر استفاده از زیرلایه گرافنی بر روی جذب نانوپوستههای فلزی کروی طلا Au و نقره Ag مورد بررسی قرار گرفته است. در این بررسی ها برای هر کدام از دو پوسته فلزی مذکور به طور جداگانه سه نوع هسته دی‌الکتریک متفاوتِ هوا Air¬، سیلیکون Si و آلومینا Al_"2" O_"3" در نظر گرفته شده¬ است. بررسی‌، شبیه ‌سازی¬ و مقایسه این نانو پوسته¬ها برای دو اندازه¬¬ی شعاع کلّ ساختار¬ برابر با 25 ‌‌نانو‌متر و 50 نانومتر، انجام گرفته است. در مطالعات انجام شده بر روی نتایج، مشاهده می‌شود حضور زیرلایه گرافنی در زیر نانو‌پوسته‌های فلزی بر میزان دامنه جذب آنها می‌افزاید. در این بین عواملی مانند اندازه ضخامت پوسته¬ی فلزیِ نانو‌پوسته، اندازه ضخامت زیرلایه گرافنی، جنس دی‌الکتریک مورد استفاده، اندازه شعاع کلّی ساختار و همچنین جنس محیط پیرامون، به شدّت در میزان بهبود و افزایش در دامنه نمودار برش مقطع عرضی جذب ACS ساختار، مؤثّر هستند و برای داشتن بیشینه¬ی جذب، باید مصالحه‌ای بین این کمیّت‌ها وجود داشته باشد.


Article's English abstract:

In ‌this article the effect of ‌using graphene substrate on absorption of spherical metallic gold Au and silver Ag nano shells has been investigated. In this study, for each one of two mentioned metallic nano shells, three kind of different dielectrics: air, silicon si and alumina Al_2 O_3, have been considered. Investigation, simulation and comparison of these nano shells have been done in two sizes of¬ structure¬ overall radius¬ equal to 25 nm and 50 nm. According to performed studies on results, it is observed that utilizing graphene substrate under metallic nano shells increases amplitude of absorption. In this case, some parameters such as, thickness of metallic nano shells, thickness of graphene substrate, material of used dielectric, overall radius of structure and also material of surrounding medium are very effective on improving and increasing amplitude of absorption cross section ACS. So, to have maximum absorption, a trade of should be exist among mentioned parameters.
