Structure-Property Correlations in Sb, Ge, and Ga Doped AlFeB for Magnetocaloric Applications
R. Preyadarshini, S. Kavita, Ashutosh Kumar +1
This study investigates the effects of Sb, Ge, and Ga doping in AlFeB on magnetic and magneto-caloric properties. Samples of AlFeB and AlFeMB (M…
Structural and Thermoelectric Properties of AlFeMB (M=Ag, Ni, Sb, Ga, and Ge) Intermetallic Borides
D. Sivaprahasam, R. Preyadarshini, Ashutosh Kumar
AlFeB, a ternary transition metal boride doped with Ag, Ni, Sb, Ga, and Ge was investigated for the phase constituents, microstructure, and thermoelectric properties. The p…
Effect of crystal field engineering and Fermi level optimization on thermoelectric properties of GeTe: Experimental investigation and theoretical insight
Ashutosh Kumar, Preeti Bhumla, D. Sivaprahasam +2
This study shows a method of enhancing the thermoelectric properties of GeTe-based materials by Ti and Bi co-doping on cation sites along with self-doping with Ge via simultaneous…
Improved Thermoelectric Properties in (1-x)LaCoO3/(x)La0.7Sr0.3CoO3 Composite
Ashutosh Kumar, D. Sivaprahasam, Ajay D. Thakur
A high Seebeck coefficient (S), large electrical conductivity (σ), and reduced thermal conductivity (κ) are required to achieve a high figure-of-merit (zT) in an ideal thermoelectr…
Colossal Seebeck coefficient in Aurivillius Phase-Perovskite Oxide Composite
Ashutosh Kumar, D. Sivaprahasam, Ajay D. Thakur
We propose an inexpensive scalable approach for achieving extremely high values of Seebeck coefficient () by exploiting the natural superlattice structure in Aurivillius phase o…
Thermoelectric Properties of (1-x)LaCoOLaSrMnO Composite
Ashutosh Kumar, Karuna Kumari, B. Jayachandran +2
We report the thermoelectric (TE) properties of (1-x)LaCoO3.xLa0.7Sr0.3MnO3 (0 < x < 0.10) composite in a temperature range 320-800 K. Addition of La0.7Sr0.3MnO3 to LaCoO3 in small…
