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 ...
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
conclusions all treatment modalities showed a significant analgesic effect on cnbp in rats, being most prominent with the quantum light therapy. results analgesic effects were observed with all treatment regimens; however, the most prominent median analgesic effect was shown in the quantum light therapy in combination with acupuncture for estrogen-induced cnbp (pf1 = 663.9, pf2 = 403.4) (p = 0....
چکیده ندارد.
the combined effect of hydrostatic pressure and temperature on correlation energy in a triplet state of two electron spherical quantum dot with square well potential is computed. the result is presented taking gaas dot as an example. our result shows the correlation energies are i)negative in the triplet state contrast to the singlet state ii) it increases with increase in pressure iii)further...
