Quantum oscillations in an optically-illuminated two-dimensional electron system at the LaAlO/SrTiO interface
I. Leermakers, K. Rubi, M. Yang +9
We have investigated the illumination effect on the magnetotransport properties of a two-dimensional electron system at the LaAlO/SrTiO interface. The illumination signific…
Extremely high magnetoresistance and conductivity in the type-II Weyl semimetals WP2 and MoP2
Nitesh Kumar, Yan Sun, Nan Xu +12
The peculiar band structure of semimetals exhibiting Dirac and Weyl crossings can lead to spectacular electronic properties such as large mobilities accompanied by extremely high m…
Extremely high conductivity observed in the triple point topological metal MoP
Nitesh Kumar, Yan Sun, Michael Nicklas +20
Weyl and Dirac fermions have created much attention in condensed matter physics and materials science. Recently, several additional distinct types of fermions have been predicted.…
Observation of pseudo two dimensional electron transport in the rock salt type topological semimetal LaBi
Nitesh Kumar, Chandra Shekhar, Shu-Chun Wu +5
Topological insulators are characterized by an inverted band structure in the bulk and metallic surface states on the surface. In LaBi, a semimetal with a band inversion equivalent…
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…
