[ 1 ] - Simulation of Direct Pumping of Quantum Dots in a Quantum Dot Laser
In this paper, the nonlinear rate equations governing a quantum dot laser isused to simulate the transient as well as the steady-state behaviors of the laser.Computation results show that the rate equations are capable of simulating true behaviorof a quantum dot laser. Then, the pump rates of the rate equations (which show indirectelectrical pumping of the quantum dots through a wetting layer) ...
[ 2 ] - Numerical Calculation of Resonant Frequencies and Modes of a Three-Atom Photonic Molecule and a Photonic Crystal in an External Cavity
In the present paper, resonant frequencies and modes of a three-atom photonic molecule and a photonic crystal placed within a cavity are numerically calculated. First, governing formulation in transverse electric field mode (TE) is obtained using Maxwell equations. Then, an algorithm based on a finite difference scheme and matrix algebra is presented. The algorithm is then implemented in a comp...
[ 3 ] - Simulation of Surface Plasmon Excitation in a Plasmonic Nano-Wire Using Surface Integral Equations
In this paper, scattering of a plane and monochromatic electromagnetic wave from a nano-wire is simulated using surface integral equations. First, integral equationsgoverning unknown fields on the surface is obtained based on Stratton-Cho surface integral equations. Then, the interaction of the wave with a non-plasmonic as well as a palsmonic nano-wire is considered. It is shown that in scatter...
[ 4 ] - Simulation of Light-Nanowire Interaction in the TE Mode Using Surface Integral Equations
In this paper, the scattering of a plane monochromatic electromagnetic wave from a nanowire with circular cross-section in the transverse electric (TE) mode is simulated using the well-known Stratton-Chu surface integral equations. For an ordinary dielectric nanowire the refraction phenomenon is nicely simulated. In the case of a plasmonic nanowire no sign of surface plasmon excitation and prop...
[ 5 ] - Synthesis of Copper Hydroxide Nitrate (Cu2(OH)3NO3) Micro-Sheets by Plasma Electrolysis of Cu(NO3)2 Aqueous Solution in Atmospheric Air
In the present paper, using a cathodic pin-to-solution electrical discharge electrolysis setup, interaction of the atmospheric air plasma with aqueous solution of copper nitrate and its possibility for synthesis of nano-materials is investigated. An AC (50 Hz) high-voltage power supply (5 kV) with rectified current is used for electrical discharge of the air between a metal pin and the solution...
[ 6 ] - بررسی محاسباتی اثر تفاوت جرم الکترون و حفره بر ممان دوقطبی الکتریکی اکسیتون در نقطۀ کوانتومی مخروطی
در مقالۀ حاضر، توابع موج اکسیتونی و ممان دوقطبی الکتریکی مربوط به آنها در یک نقطۀ کوانتومی مخروطی با قاعدۀ کروی به صورت عددی محاسبه می‌شود. برای انجام محاسبات از یک کد رایانه‌ای استفاده می‌شود که نویسندگان برای حل معادلۀ شرودینگر بر اساس روش اختلالی ”برهمکنش پیکربندی“ تدوین کرده‌اند. نتایج محاسبات نشان می‌دهد که اگر جرم مؤثر الکترون و حفره با هم برابر باشد آنگاه ممان دوقطبی اکسیتون برای تمام وی...
