Abstract Scope |
We will present our recent results on intermetallic and chalcogenide materials which were selected for their low cost and/or advantageous properties. For example, the incommensurate compounds MnSiγ (γ ~ 1.73) and FeGeγ (γ ~ 1.52) were studied through high temperature XRD to assess their crystal structure and thermoelectric properties stability. MnSiγ is particularly interesting as it exhibits sufficiently high ZT values (≥ 0.5 at 500 °C) in a wide temperature range, which is an advantage for stable electricity production. These advantages render them ideal candidates for the development of industrial prototypes. We also focused on the case of Ti/Zr doped SnTe which were found to be efficient dopants for SnTe to realize a stable and improved thermoelectric performance for mid temperature regime (323 – 723 K) and by codoping the optimized Ti/Zr-doped SnTe with Mn, remarkably enhancing the device/average zT (zTave). |
