Bing Lv,Yucheng Lan,Xiqu Wang,Qian Zhang,Yongjie Hu,Allan J. Jacobson,David Broido,Gang Chen,Zhifeng Ren,Ching-Wu Chu,Ching-Wu Chu +10 more
TL;DR: In this paper, a cubic boron arsenide (BAs) crystal with a zinc blende cubic structure and lattice parameters of a 4.7830(7) A was synthesized and characterized, achieving a relatively high thermal conductivity of ∼200 Wm−1 K−1.
Journal ArticleDOI
Optimization of hierarchical structure and nanoscale-enabled plasmonic refraction for window electrodes in photovoltaics
Bing Han,Qiang Peng,Ruopeng Li,Qikun Rong,Yang Ding,Eser Metin Akinoglu,Xueyuan Wu,Xin Wang,Xubing Lu,Qianming Wang,Guofu Zhou,Jun-Ming Liu,Jun-Ming Liu,Zhifeng Ren,Michael Giersig,Michael Giersig,Andrzej Herczynski,Krzysztof Kempa,Krzysztof Kempa,Jinwei Gao +19 more
TL;DR: It is shown that elements of hierarchal topology, rather than details of the branching geometry, are of primary importance in optimizing the networks, and demonstrate this experimentally on five model artificial hierarchical networks of varied levels of complexity.
Journal ArticleDOI
Shape evolution of lead telluride and selenide nanostructures under different hydrothermal synthesis conditions.
TL;DR: Face-open nanoboxes of lead telluride and selenide have been synthesized by a simple hydrothermal method, opening a new route to prepare hierarchical structures of a variety of binary semiconducting materials in a large quantity.
Journal ArticleDOI
Enhancement of field emission of aligned carbon nanotubes by thermal oxidation
TL;DR: In this paper, postgrowth thermal annealing was conducted at 850°C for 1h in vacuum plus at 465°C in air for 2h in air to improve the field emission current density of carbon nanotubes.
Journal ArticleDOI
The influence of doping sites on achieving higher thermoelectric performance for nanostructured α-MgAgSb
Zihang Liu,Zihang Liu,Yumei Wang,Yumei Wang,Weihong Gao,Jun Mao,Huiyuan Geng,Jing Shuai,Wei Cai,Jiehe Sui,Zhifeng Ren +10 more
TL;DR: In this article, the effect of doping site on the carrier transport behavior of nanostructured α-MgAgSb was investigated, and it was demonstrated that Ca doping on the Mg site leads to higher mobility and power factor in comparison with doping on Sb site, originated from the less introduced perturbation to valence band upon doping.
