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 اولEXCITON LOCALIZATION IN InGaN/GaN QUANTUM WELLS
Time-resolved cathodoluminescence (CL) techniques have been employed to examine the optical properties and kinetics of carrier relaxation in a InGaN/GaN single quantum well (QW) sample. CL images of the QW sample revealed a spotty cellular pattern indicative of local In compositional variations, which induce local potential fluctuations and result in a strong lateral excitonic localization at I...
متن کاملCharged exciton dynamics in GaAs quantum wells
We study the dynamics of the charged and neutral excitons in a modulation-doped GaAs quantum well by time-resolved photoluminescence under a resonant excitation. The radiative lifetime of the charged exciton is found to be surprisingly short, 60 ps. This time is temperature independent between 2 and 10 K, and increases by a factor of 2 at 6 T. We discuss our findings in view of present theories...
متن کاملExciton - exciton interactions in quantum wells . Optical properties and energy and spin relaxation
The gas of interacting excitons in quantum wells is studied. We obtain the Hamiltonian of this gas by the projection of the electron-hole plasma Hamiltonian to exciton states and an expansion in a small density. Matrix elements of the exciton Hamiltonian are rather sensitive to the geometry of the heterostructure. The mean field approximation of the exciton Hamiltonian gives the blue shift and ...
متن کاملExciton Spin Dynamics in Semiconductor Quantum Wells
1.1 Two-Dimensional exciton fine structure The spin properties of excitons in nanostructures are determined by their fine structure. Before analysing the exciton spin dynamics, we give first a brief description of the exciton states in quantum wells. We will mainly focus in this review on GaAs or InGaAs quantum well which are model systems. For more details, the reader is referred to the review...
