High Entropy Alloy CrFeNiCoCu sputtered films
J. Mayandi, M. Schrade, P. Vajeeston +10
High entropy alloy(HEA) films of CrFeCoNiCu were prepared by sputtering, their structure was characterized, and their electric properties measured by temperature dependent Hall and…
Shallow impurity band in ZrNiSn
Matthias Schrade, Kristian Berland, Andrey Kosinskiy +2
ZrNiSn and related half Heusler compounds are candidate materials for efficient thermoelectric energy conversion with a reported thermoelectric figure-of-merit of n-type ZrNiSn exc…
Using the Callaway model to deduce relevant phonon scattering processes: The importance of phonon dispersion
Matthias Schrade, Terje G. Finstad
The thermal conductivity of a material is an important parameter in many different applications. Optimization strategies of often require insight into the dominant phonon s…
A Study of S doped ZnSb
X. Song, T. G. Finstad
We report on S-doping of ZnSb for S concentrations ranging from 0.02 at% to 2.5 at%. There are no previous reports on S-doping. ZnSb is a thermoelectric material with some advantag…
The role of grain boundary scattering in reducing the thermal conductivity of polycrystalline XNiSn (X = Hf, Zr, Ti) half-Heusler alloys
Matthias Schrade, Kristian Berland, Simen N. H. Eliassen +10
Thermoelectric application of half-Heusler compounds suffers from their fairly high thermal conductivities. Insight into how effective various scattering mechanisms are in reducing…
Enhancement of thermoelectric properties by energy filtering: Theoretical potential and experimental reality in nanostructured ZnSb
Kristian Berland, Xin Song, Patricia A. Carvalho +3
Energy filtering has been suggested by many authors as a means to improve thermoelectric properties. The idea is to filter away low-energy charge carriers in order to increase Seeb…
