Analysis of Kirk Effect in Nanoscale Quantum Well Heterojunction Bipolar Transistor Laser

In this paper, we present an analytical model to analysis the kirk effect onstatic and dynamic responses of quantum well heterojunction bipolar transistor lasers(HBTLs). Our analysis is based on solving the kirk current equation, continuityequation and rate equations of HBTL. We compare the performance (current gain,output photon number and small signal modulation bandwi...

بررسی عوامل افزایش بازده در سلول خورشیدی ناهمجنس با نقاط کوانتومی

ضخامت لایۀ­ نقاط کوانتومی و نیمه­رسانای شفاف با شکاف بزرگ، میزان ناخالصی لایۀ نقاط کوانتومیو نوع فلز آند از جمله عوامل تأثیرگذار بر بازدهِ سلول­های خورشیدی نقطۀ کوانتومی ناهمجنس (HQDSC) می­باشند. در این مقاله با استفاده از نرم­افزار کامسول نسخه 4/5، ابتدا سلولی شامل یک لایه از نقاط کوانتومی سولفید سرب (PbS) پوشیده از لیگاندهای کوتاه و یک لایه نیمه­رسانای اکسید روی (ZnO) و آندی از جنس طلا شبیه­سا...

Quantum dot defined in a two-dimensional electron gas at a n-AlGaAs ÕGaAs heterojunction: Simulation of electrostatic potential and charging properties

We present a self-consistent Schrödinger–Poisson scheme for simulation of electrostatic quantum dots defined in gated two-dimensional electron gas formed at n-AlGaAs /GaAs heterojunction. The computational method is applied to a quantitative description of transport properties studied experimentally by Elzermann et al. Appl. Phys. Lett. 84, 4617 2004 . Our three-dimensional model describes the ...
