Quantum oscillations and the Fermi-surface topology of the Weyl semimetal NbP
J. Klotz, Shu-Chun Wu, Chandra Shekhar +8
The Weyl semimetal NbP was found to exhibit topological Fermi arcs and exotic magneto-transport properties. Here, we report on magnetic quantum-oscillation measurements on NbP and…
Nearly-free electrons in a 5d delafossite oxide metal
Pallavi Kushwaha, Veronika Sunko, P. J. W. Moll +11
Understanding the role of electron correlations in strong spin-orbit transition-metal oxides is key to the realisation of numerous exotic phases including spin-orbit assisted Mott…
Synthesis and Crystal Growth of Tetragonal Fe1.00Se
Cevriye Koz, Marcus Schmidt, Horst Borrmann +6
Single crystals of tetragonal Fe1.00Se were grown from polycrystalline material by chemical vapor transport reaction at temperatures below 723 K using AlCl3 as transport additive.…
Superconductivity in Weyl Semimetal Candidate MoTe2
Yanpeng Qi, Pavel G. Naumov, Mazhar N. Ali +19
In recent years, layered transition-metal dichalcogenides (TMDs) have attracted considerable attention because of their rich physics; for example, these materials exhibit supercond…
Negative magnetoresistance without well-defined chirality in the Weyl semimetal TaP
Frank Arnold, Chandra Shekhar, Shu-Chun Wu +15
Weyl semimetals (WSMs) are topological quantum states wherein the electronic bands linearly disperse around pairs of nodes, the Weyl points, of fixed (left or right) chirality. The…
Extremely large magnetoresistance and ultrahigh mobility in the topological Weyl semimetal NbP
Chandra Shekhar, Ajaya K. Nayak, Yan Sun +10
Recent experiments have revealed spectacular transport properties of conceptually simple semimetals. For example, normal semimetals (e.g. WTe) have started a new trend to reali…
