Journal ArticleDOI
Tellurium doped n-type Zintl Zr3Ni3Sb4 thermoelectric materials: Balance between carrier-scattering mechanism and bipolar effect
Zihang Liu,Jun Mao,Shengyuan Peng,Binqiang Zhou,Weihong Gao,Jiehe Sui,Yanzhong Pei,Zhifeng Ren +7 more
TL;DR: In this article, a relatively good ZT of ∼0.6 was achieved by Te doping on the Sb site, which can be attributed to the combination of high majority-carrier concentration and enlarged band gap.
Journal ArticleDOI
Mechanical properties of nanostructured thermoelectric materials α-MgAgSb
Zihang Liu,Zihang Liu,Weihong Gao,Xianfu Meng,Xiaobo Li,Jun Mao,Yumei Wang,Yumei Wang,Jing Shuai,Wei Cai,Zhifeng Ren,Jiehe Sui +11 more
TL;DR: In this article, a detailed study on the mechanical properties of nanostructured α-MgAgSb is presented, where the Young's modulus, nanoindentation hardness, compressive strength, and fracture toughness are compared with other p-type thermoelectric materials.
Journal ArticleDOI
Theoretical studies on the thermoelectric figure of merit of nanograined bulk silicon
TL;DR: In this paper, the authors investigated the phonon transport in silicon nanocomposites using Monte Carlo simulations considering frequency-dependent phonon mean free paths, and combined the phonons modeling with electron modeling to predict the thermoelectric figure of merit (ZT) of silicon nano-composites.
Journal ArticleDOI
VS4 with a chain crystal structure used as an intercalation cathode for aqueous Zn-ion batteries
TL;DR: In this paper, vanadium tetrasulfide (VS4) with a beneficial one-dimensional atomic-chain structure is reported to serve as a favorable intercalation cathode material for high-performance Zn-ion batteries.
Journal ArticleDOI
A hot-wire probe for thermal measurements of nanowires and nanotubes inside a transmission electron microscope
Chris Dames,Shih-Chi Chen,Charles Thomas Harris,Jian Yu Huang,Zhifeng Ren,M. S. Dresselhaus,Gang Chen +6 more
TL;DR: A hot wire probe has been developed for use inside a transmission electron microscope to measure the thermal resistance of individual nanowires, nanotubes, and their contacts to minimize the effects of thermal expansion, intrinsic thermal vibrations, and Lorentz forces.
