“…Impurity band conduction has been reported in many materials [80][81][82]. It was also observed for ZnSb by Justi et al in the 1960s [14]. Recently, several others have reported on impurity bands in ZnSb [53,79,83].…”

“…A similar transition from n-type to p-type also occurs in the related compound CdSb, which has been attributed to Cd-vacancies [75]. for polycrystalline samples without intended dopants [14,45]. This deviation is considered due to the intrinsic defects, giving a net hole concentration.…”

“…However, the n-type conduction did not always occur. Justi et al did not achieve n-type ZnSb with Ga despite several attempts with single and polycrystalline ZnSb [14]. Niedziolka et al predicted theoretically by DFT calculations that boron would electronically be a good candidate for n-type ZnSb, but did not succeed to synthesize the material and ascribed it to the high formation energy of a boron atom on a Zn site [36].…”

“…The purity of the starting elemental zinc and antimony materials has a significant impact on the resulting electrical properties. For example, starting materials with purities of 99.99% and 99.9999% allows to obtain the charge carrier concentration of ∼10 , respectively, on undoped polycrystalline ZnSb [14]. Since ZnSb does not melt congruently, solidification will result in a mix of the phases, Zn 4 Sb 3 , ZnSb and Sb.…”

“…Since ZnSb does not melt congruently, solidification will result in a mix of the phases, Zn 4 Sb 3 , ZnSb and Sb. This mix can be homogenized by sufficient heat treatments to reach the thermodynamic equilibrium state with a single uniform ZnSb phase [14,15]. Another problem with the solidification is that the sample contains cracks that significantly influence on the electron transport [13].…”

The thermoelectric material ZnSb has been studied intensively in recent years and has shown promising features. The other zinc-antimonide compound, Zn 4 Sb 3 has remarkable low thermal conductivity, but it is accompanied with phase transitions at moderate temperature and has inherent stability problems. Compared to that, ZnSb is relatively phase stable and has a relative high charge carrier mobility and Seebeck coefficient, thus yielding a decent power factor. Meanwhile, its thermal conductivity can be reduced by means of nanostructuring, thus giving a good figure of merit at moderate temperatures, 400-600K. Many researchers have dedicated their efforts to study and improve ZnSb properties, and the figure of merit has been reported to be above one. Still, ZnSb as a thermoelectric material has features and behaviours that are not well-understood. The behaviour and properties of its intrinsic defects are not understood, but have interested researchers in recent years. This chapter intends to offer a comprehensive review on ZnSb to the readers. By combining own experiences from research on thermoelectric materials, the authors address the prospect for improving the thermoelectric properties of ZnSb and the concerns of transferring lab results to manufacturing.

Doping of p‐type ZnSb: Single parabolic band model and impurity band conduction

Even though the ZnSb compound has been known for decades and used in the earliest thermoelectric devices, the potential of the material as a modern thermoelectric may be underestimated. We synthesized p‐type doped samples using ball‐milling and hot‐pressing and measured their thermoelectric properties including mobility and carrier concentration. Establishing a single parabolic band (SPB) model using these measurements on the Cu, Sn, and self‐doped samples allows for predictions on the optimum thermoelectric efficiency. It is projected to reach zT = 0.75 at 700 K. Deviations from the SPB model at low carrier concentrations are discussed and impurity band conduction is brought in as a possible explanation.
