Tuneable local order in thermoelectric crystals
Nikolaj Roth, Jonas Beyer, Karl F. F. Fischer +3
Although crystalline solids are characterized by their periodic structures, some are only periodic on average and deviate on a local scale. Distinct local orderings can exist with…
Growth and transport properties of Mg3X2 (X = Sb, Bi) single crystals
Jiazhan Xin, Guowei Li, Gudrun Auffermann +7
The discovery of high thermoelectric performance in n-type polycrystalline Mg3(Sb,Bi)2 based Zintl compounds has ignited intensive research interest. However, some fundamental ques…
Establishing the carrier scattering phase diagram for ZrNiSn-based half-Heusler thermoelectric materials
Qingyong Ren, Chenguang Fu, Qinyi Qiu +15
Chemical doping is one of the most important strategies for tuning electrical properties of semiconductors, particularly thermoelectric materials. Generally, the main role of chemi…
A simple model for vacancy order and disorder in defective half-Heusler systems
Nikolaj Roth, Tiejun Zhu, Bo Brummerstedt Iversen
Defective half-Heusler systems X(1-x)YZ with large amounts of intrinsic vacancies, such as Nb(1-x)CoSb, Ti(1-x)NiSb and V(1-x)CoSb, are a group of promising thermoelectric material…
