Journal ArticleDOI
Suppression of recombination in waveguide in c-plane InGaN-based green laser diodes
Yang Cheng,Yang Cheng,Jianping Liu,Jianping Liu,Liqun Zhang,Liqun Zhang,Desheng Jiang,Aiqin Tian,Aiqin Tian,Feng Zhang,Feng Zhang,Meixin Feng,Meixin Feng,Pengyan Wen,Pengyan Wen,Wei Zhou,Wei Zhou,Shuming Zhang,Shuming Zhang,Masao Ikeda,Masao Ikeda,Deyao Li,Deyao Li,Hui Yang,Hui Yang +24 more
TL;DR: In this paper, a potential barrier located at the interface between GaN last barrier and InGaN upper waveguide layer was found to cause strong recombination in upper waveguarantee layer and lower the carrier injection efficiency of green laser diodes when In content is higher than 4%.
Journal ArticleDOI
Catalyst-free curing and closed-loop recycling of carboxylated functionalized rubber by a green crosslinking strategy
TL;DR: In this paper, a facile and high-efficiency green crosslinking strategy for the carboxyl-functionalized rubber was reported, which offers a promising way for high-efficient crosslink of diene rubber as well as a real cost-effective and environmentally friendly recovery of end of life rubber materials.
Journal ArticleDOI
Comparative full-length transcriptome analysis provides novel insights into the regulatory mechanism of natural rubber biosynthesis in Taraxacum kok-saghyz Rodin roots
TL;DR: In this paper, a comparative transcriptome analysis was conducted between the lines containing high rubber (HR) and low rubber (LR) contents, and a total of 3134 differentially expressed genes (DEGs) were identified.
Journal ArticleDOI
Luminescence of EPDM rubber ultrafine fibers containing nanodispersed Eu-complexes
TL;DR: In this paper, the dispersion of Eu-complexes in the fibers was characterized by transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDS), and XRD.
Journal ArticleDOI
Improvement of Ohmic contact to p-GaN by controlling the residual carbon concentration in p ++ -GaN layer
Feng Liang,Degang Zhao,Desheng Jiang,Zongshun Liu,Jianjun Zhu,Ping Chen,Jing Yang,Wei Liu,Xiang Li,Shuangtao Liu,Yao Xing,Liqun Zhang,Hui Yang,Heng Long,Mo Li +14 more
TL;DR: In this article, growth conditions were used to control the residual carbon impurity incorporation in p++-GaN layers, and the specific contact resistance (ρc) with various residual carbon concentrations was investigated through the circular transmission line model (CTLM) method and secondary ion mass spectroscopy (SIMS) analysis.
