Topological semimetals (TSMs) are characterized by bulk band crossings in their electronic
structures, which are expected to give rise to gapless electronic excitations and topological …

Long after the heady days of high‐temperature superconductivity, the oxides came back into
the limelight in 2004 with the discovery of the 2D electron gas (2DEG) in SrTiO3 (STO) and …

The recent discovery of Weyl and Dirac semimetals is one of the most important progresses
in condensed matter physics. Among the very few available tools to characterize Weyl …

Topological insulators (TIs) hold promise as a platform for unique quantum phenomena.
However, realizing these phenomena experimentally requires sophisticated devices. In this …

Strain can be used to modify the band structure—and thus the electronic properties—of two-
dimensional materials. However, research has focused on the use of monolayer graphene …

We review theoretical and experimental highlights in transport in two-dimensional
topological materials over the last five years. Topological materials comprise topological …

Among the perovskite oxide family, KTaO3 (KTO) has recently attracted considerable
interest as a possible system for the realization of the Rashba effect. In this work, we report a …

An intriguing property of a three-dimensional (3D) topological insulator (TI) is the existence
of surface states with spin-momentum locking, which offers a new frontier of exploration in …

Anisotropic magnetoresistance is the change tendency of resistance of a material on the
mutual orientation of the electric current and the external magnetic field. Here, we report …

We measure the low-temperature magnetic transport in a recently discovered type-II Dirac
semimetal NiTe 2 and successfully observe the planar Hall effect (PHE) which is often …
