还在等什么,快来看看这篇量子阱(quantumwell)百科中学物理吧~ 量子阱〔quantumwell〕 量子阱(quantumwell) 量子阱是一种人工设计采用外延方法生长的半导体微结构。其主要特性是电子(空穴,有时还包括光子)在空间上被限制在一个很薄的区域内运动,该区域的厚度小于电子的德布罗意波长,电子(空穴)行为表现出二维特征。
图11. 以lump-element电路表示的 PN 结移相器的数值 EO 响应。 通过在Quantum-Well Slab Wings中引入量子约束高迁移率载流子,可以在不增加光损耗的情况下大幅降低串联电阻。这克服了传统的带宽-损耗权衡,有可能使硅基光电子调制器的工作频率超过 200 Gbaud,用于下一代超大容量光网络。 参考文献 [1] K. Ogawa, ...

A two-dimensional (2D) quantum well structure consists of a very thin layer of material that is nanometers thick in one dimension and semi-infinitely large in the other two dimensions. From: Progress in Materials Science, 2013 About this pageSet alert ...
A Multiple Quantum Well refers to a structure consisting of thin conducting layers separated by wide barriers, typically used in experiments on long time spin relaxation to enhance the measured signal and reduce relative noise. AI generated definition based on: Physica E: Low-dimensional Systems and...
The cross-sectional morphology and atomic composition of samples before and after nitrogen ion implantation were compared and analyzed by high-resolution transmission electron microscopy and energy-dispersive x-ray. Results show that Ga and Al atoms diffuse among the quantum well, barrier, and waveguide...
State densities g(epsilon) to energy epsilon of a single quantum well are changed stepwise respectively for electrons (a), light holes (b), and heavy holes (c). Because this element is formed with large internal loss alphai, the total loss alphatotal becomes large. Therefore, laser ...
PURPOSE: To stably oscillate a short-wavelength laser at a low threshold value by a method wherein a quantum-well structure provided with at least one quantum well in which a well layer has been sandwiched between barrier layers which are nearly lattice-matched to the well layer and whose ban...
in Fig.3c, the ASE peak emerges at the red side of the absorption where the emitted photon at the ASE wavelength is absorbed insignificantly. This phenomenon was observed in gain media of colloidal CQDs2, epitaxially-grown II–VI quantum well lasers27, and organic dyes28as reported previously...
