Tunable Circular Photogalvanic and Photovoltaic Effect in 2D Tellurium with Different Chirality
Chang Niu, Shouyuan Huang, Neil Ghosh +5
Chirality arises from the asymmetry of matters, where two counterparts are the mirror image of each other. The interaction between circular-polarization light and quantum materials…
Bilayer Quantum Hall States in an n-type Wide Tellurium Quantum Well
Chang Niu, Gang Qiu, Yixiu Wang +3
Tellurium (Te) is a narrow bandgap semiconductor with a unique chiral crystal structure. The topological nature of electrons in the Te conduction band can be studied by realizing n…
Raman Response and Transport Properties of One-Dimensional van der Waals Tellurium Nanowires
Jing-Kai Qin, Pai-Ying Liao, Mengwei Si +15
Tellurium can form nanowires of helical atomic chains. Given their unique one-dimensional van der Waals structure, these nanowires are expected to show remarkably different physica…
Gate-tunable Strong Spin-orbit Interaction in Two-dimensional Tellurium Probed by Weak-antilocalization
Chang Niu, Gang Qiu, Yixiu Wang +4
Tellurium (Te) has attracted great research interest due to its unique crystal structure since 1970s. However, the conduction band of Te is rarely studied experimentally because of…
Quantum Hall Effect of Weyl Fermions in Semiconducting n-type Tellurene
Gang Qiu, Chang Niu, Yixiu Wang +4
Dirac and Weyl nodal materials can host low-energy relativistic quasiparticles. Under strong magnetic fields, the topological properties of Dirac/Weyl materials can directly manife…
Imaging Carrier Inhomogeneities in Ambipolar Tellurene Field Effect Transistors
Samuel Berweger, Gang Qiu, Yixiu Wang +7
Developing van der Waals (vdW) homojunction devices requires materials with narrow bandgaps and simultaneously high hole and electron mobilities for bipolar transport, as well as m…
