High Fermi velocities and small cyclotron masses in LaAlGe
Zhixiang Hu, Qianheng Du, Yu Liu +2
We report quantum oscillation measurements of LaAlGe, a Lorentz-violating type-II Weyl semimetal with tilted Weyl cones. Very small quasiparticle masses and very high Fermi velocit…
Low-Temperature Thermopower in CoSbS
Qianheng Du, Milinda Abeykoon, Yu Liu +2
We report giant thermopower S = 2.5 mV/K in CoSbS single crystals, a material that shows strong high-temperature thermoelectric performance when doped with Ni or Se. Changes of low…
Vacancy defect control of colossal thermopower in FeSb2
Qianheng Du, Lijun Wu, Huibo Cao +9
Iron diantimonide is a material with the highest known thermoelectric power. By combining scanning transmission electron microscope study with electronic transport neutron, X-ray s…
Surface Conductivity in Antiferromagnetic Semiconductor CrSb
Qianheng Du, Huixia Fu, Junzhang Ma +4
The contribution of bulk and surface to the electrical resistance along crystallographic \textit{b}- and \textit{c}-axes as a function of crystal thickness gives evidence for a tem…
Room-Temperature Skyrmion Thermopower in Fe3Sn2
Qianheng Du, Myung-Geun Han, Yu Liu +3
We present first room-temperature thermoelectric signature of the skyrmion lattice. This was observed in Fe3Sn2, a Kagome Dirac crystal with massive Dirac fermions that features hi…
Magnetic-field control of topological electronic response near room temperature in correlated Kagome magnets
Yangmu Li, Qi Wang, Lisa DeBeer-Schmitt +13
Strongly correlated Kagome magnets are promising candidates for achieving controllable topological devices owing to the rich interplay between inherent Dirac fermions and correlati…
