Large non-saturating Nernst thermopower and magnetoresistance in compensated semimetal ScSb
Antu Laha, Sarah Paone, Niraj Aryal +1
Today, high-performance thermoelectric and thermomagnetic materials operating in the low-temperature regime, particularly below the boiling point of liquid nitrogen remain scarce.…
Single crystalline orthorhombic GdAlGe as a rare earth magnetic Dirac nodal-line metal
Antu Laha, Juntao Yao, Asish K. Kundu +11
Crystal engineering is a method for discovering new quantum materials and phases, which may be achieved by external pressure or strain. Chemical pressure is unique in that it gener…
Nernst power factor and figure of merit in compensated semimetal ScSb
Antu Laha, Sarah Paone, Asish K. Kundu +4
Recently, topological semimetals have emerged as strong candidates for solid state thermomagnetic refrigerators due to their enhanced Nernst effect. This enhancement arises from th…
Topological phase transition and phonon-space Dirac topology surfaces in ZrTe
Niraj Aryal, Xilian Jin, Q. Li +2
We use first-principles methods to reveal that in ZrTe, a layered van der Waals material like graphite, atomic displacements corresponding to five of the six zone-center A…
