در این پایان نامه، فشار کوانتومی وارد بر تیغه ی دی الکتریک تقویت کننده بررسی شده است. برای انجام این کار، ابتدا میدان الکترومغناطیسی در حضور تیغه ی دی الکتریک تقویت کننده به روش تابع گرین کوانتیزه شده است. برای سادگی محاسبات، فرمولبندی به حالت یک بعدی اختصاص داده شده است. سپس مفهوم عملگر فشار تابشی با استفاده از تانسور تنش ماکسول معرفی شده است. مقدار چشمداشتی این عملگر برای حالتی که میدان تابشی...

The present study was conducted to investigate current density of0.3 0.7 Al Ga N/ GaN multiple quantum well solar cell (MQWSC) under hydrostaticpressure. The effects of hydrostatic pressure were taken into account to measureparameters of 0.3 0.7 Al Ga N/ GaN MQWSC, such as interband transition energy, electronholewave functions, absorption coefficient, and dielectric con...

In this paper, we investigated the corrected plasmon dispersion relation for graphene in presence of a constant magnetic field which it includes a quantum term arising from the collective electron density wave interference effects. By using quantum hydrodynamic plasma model which incorporates the important quantum statistical pressure and electron diffraction force, the longitudinal plasmons ar...

In this paper, by using a quantum hydrodynamic plasma model which incorporates the important quantum statistical pressure and electron diffraction force, we present the corrected plasmon dispersion relation for graphene which includes a k quantum term arising from the collective electron density wave interference effects (which  is integer and constant and k is wave vector). The longitudinal ...
