Reform of Object Oriented Programming Based on Task Driven and Blended Teaching

Autor: Wei Wu, Changkui Hu, Songhua Xie, Lili Fan

Publikováno v: 2020 The 4th International Conference on Education and E-Learning.

By making full use of the existing online resources and taking China University MOOC and PTA platform as the supporter, we use the existing flipped classroom experience, plan and reconstruct the original teaching process. Then a blended teaching mode

Determining the spatial profiles of electron and hole concentration, radiative and non-radiative recombination rate near a dislocation defect by combining Raman and photoluminescence imaging

Autor: Heng Lv, Qiong Chen, Fengxiang Chen, T. H. Gfroerer, Mark Wanlass, Yong Zhang, Changkui Hu

Publikováno v: 2018 IEEE 7th World Conference on Photovoltaic Energy Conversion (WCPEC) (A Joint Conference of 45th IEEE PVSC, 28th PVSEC & 34th EU PVSEC).

For commonly utilized photoluminescence (PL) imaging, the spatial resolution is dictated by the carrier diffusion length rather than by that dictated by the optical system, such as diffraction limit. Here, we show that Raman imaging of the LO phonon-

Light: Science & Applications, Vol 7, Iss 1, Pp 1-8 (2018)

Carrier diffusion is of paramount importance in many semiconductor devices, such as solar cells, photodetectors, and power electronics. Structural defects prevent such devices from reaching their full performance potential. Although a large carrier d

Dynamic of the Gaussian quantum discord and effect of non-Markovian degree

Autor: Wei Wu, Changkui Hu, Xin Liu

Publikováno v: Canadian Journal of Physics. 93:481-485

We study the dynamic of the Gaussian quantum discord in a continuous-variable system subject to a common non-Markovian environment with zero-temperature. By considering an initial two-mode Gaussian symmetric squeezed thermal state, we show that Gauss
