While the absorption coefficient is found nearly independent of the injection level. The ambipolar carrier diffusion coefficient is measured by an FCA-detected transient grating. Carrier diffusion length, bulk lifetime and surface recombination velocity is also estimated....
UV-VIS absorption spectrum and its derivative of absorption spectrum were used to detemine the shift ofband-edge of optical absorptionand band gap value along with the variation of temperature. 用紫外 可见光谱和导数吸收光谱研究了纳米TiO2 的吸收带边、能隙随着煅烧温度变化而变化的情况 ,结合XRD、TG...
The first absorption coefficient spectra determined in the region of the fundamental band edge of metal-organic vapour phase grown Cd x Hg 1 x Te (CMT) with x between 0.2 and 0.3 are presented. Analysis of these spectra shows that the optical band edge correlates with α e, between 1000–...

A depth-resolved technique based on probe-pump free carrier absorption (FCA) is especially useful for measurements in thin layers. This technique is used here to characterize optical and electrical properties under a wide range of injection levels, 10 14 –10 18 cm 3 , in low-doped n -type...
释义 频带边沿 实用场景例句 全部 With the increasing deposition amount of Cu, the absorption band - edge red - shifts. 根据雷利散射引起的消光增强解释了组装体吸收带边红移的原因. 互联网 The band edge excitonic transitions were measured by the reflectivity and photoluminescence measurements. ...
Absorption peaks of excitons in CdS xSe 1x microcrystallites are clearly resolved by modulation spectroscopy, and peak shifts due to quantum confinement ef... S Nomura,T Kobayashi - 《Solid State Communications》 被引量: 57发表: 1990年 ...
The SHG efficiency with a frequency at the edge of the absorption band of PFO is greatly boosted due to the resonant nature of the χ(3) of the organic conjugated polymer. To the best of our knowledge, the EFISH modulation depth of ~422% V−1 is the highest value ever reported. ...
We assigned this peak to the 1D band‐edge absorption induced by the inverse square root divergence of 1D density of states (DOS). 展开 关键词: Quantum wires Doping Electron densities of states Electron doped superconductors Electron gas
