Pressure Effect on Superconductivity of Iron-based Arsenic-oxide ReFeAsO0.85 (Re=Sm and Nd)
Wei Yi,Liling Sun,Zhifeng Ren,Xiaoli Dong,Hua Zhang,Xi Dai,Zhong Fang,Guang-Can Che,Jie Yang,Zheng-Cai Li,Xiao-Li Shen,Fang Zhou,Zhongxian Zhao +12 more
TL;DR: In this article, pressure effect on superconducting transition temperature (Tc) of ReFeAsO0.85 and Nd FeAsO 0.85 without fluorine doping was investigated.
Journal ArticleDOI
Study on anisotropy of n-type Mg3Sb2-based thermoelectric materials
Shaowei Song,Shaowei Song,Jun Mao,Jing Shuai,Hangtian Zhu,Zhensong Ren,Udara Saparamadu,Zhongjia Tang,Bo Wang,Zhifeng Ren +9 more
TL;DR: In this article, the authors showed that texturing is good for higher thermoelectric performance, suggesting that single crystals of n-type Mg3Sb2-based Zintl compounds are worth pursuing.
Journal ArticleDOI
New Directions for Low-Dimensional Thermoelectric Materials
Mildred S. Dresselhaus,Gang Chen,Ming Y. Tang,Ronggui Yang,Hohyun Lee,Dezhi Wang,Zhifeng Ren,Jean-Pierre Fleurial,Pawan Gogna +8 more
TL;DR: In this article, the ability to achieve a simultaneous increase in the power factor and a decrease in the thermal conductivity of the same nanocomposite sample and for transport in the same direction is discussed.
Journal ArticleDOI
Enhancement of thermoelectric performance in n-type PbTe 1−y Se y by doping Cr and tuning Te:Se ratio
Eyob Kebede Chere,Qian Zhang,Kenneth McEnaney,Mengliang Yao,Feng Cao,Jingying Sun,Shuo Chen,Cyril Opeil,Gang Chen,Zhifeng Ren +9 more
TL;DR: In this article, the authors reported a systematic study of Cr doping in PbTe1−ySey with y=0, 0.015Pb0.985Te0.75Se0.01Pb 0.99Te 0.25Se 0.75 Se0.25 was obtained due to a lowered thermal conductivity and enhanced power factor.
Controlled improvement in specific contact resistivity for thermoelectric
Patrick J. Taylor,Jay R. Maddux,Greg Meissner,Rama Venkatasubramanian,G. E. Bulman,Jonathan Pierce,Rahul P. Gupta,Jim Bierschenk,Chris Caylor,Jonathan D’Angelo,Zhifeng Ren +10 more
TL;DR: In this article, IBE donors and acceptors were ion-implanted into n-type and p-type (Bi,Sb)2(Se,Te)3 materials, respectively, to achieve >10 times higher doping at the surface.
