Consistency Check of Segregation Energies of Elements at Ni and Fe Grain-Boundaries
Wilfried Wunderlich
The need for advanced functional materials is expected to provide a boost in powder metallurgy, where the impurities on powder surfaces is incorporated as at grain boundary segrega…
SPS-Sintered NaTaO3-Fe2O3 Composite exhibits Large Seebeck Coefficient and Electric Current
Wilfried Wunderlich, Takao Mori, Oksana Sologub
NaTaO3-50wt% Fe2O3 composite ceramics showed a large Seebeck voltage of -300 mV at a temperature gradient of 650 K yielding a constant Seebeck coefficient of more than -500 microV/…
Achievements and challenges of nanostructured Titania Eco-materials derived from Sol-Gel Processing
Wilfried Wunderlich, Rino R. Mukti, Suminto Winardi +2
Nanostructured titania derived from the sol-gel processing requires a detailed study to clarify state-of-art of every process step starting from colloidal sol, peptization, gelatio…
Difference between thermo- and pyroelectric Co- based RE-(= Nd, Y, Gd, Ce)-oxide composites measured by high-temperature gradient
Wilfried Wunderlich, Hiroyuki Fujiwara
Seebeck-Voltage measurements of Cobalt-based oxide-composites containing rare-earth elements (RE= Nd, Y, Gd, Ce) were performed under high temperature gradients up to 700 K. Severa…
Screening and Fabrication of Half-Heusler phases for thermoelectric applications
Wilfried Wunderlich, Yuichiro Motoyama
Half-Heusler phases have gained recently much interest as thermoelectric materials. Screening of possible systems was performed by ab-initio simulation using VASP-software. The ene…
Effective mass calculations of SrTiO3-based superlattices for thermoelectric applications lead to new layer design
Wilfried Wunderlich, Hiromichi Ohta, Kunichi Koumoto
The effective mass is one of the main factors for enlarging the Seebeck coefficient and electronic conductivity of SrTiO3-based thermoelectric materials [1,2]. The goal of this pap…
