Evidence for pressure-induced node-pair annihilation in Cd3As2
Cheng Zhang, Jianping Sun, Fengliang Liu +12
As an intermediate state in the topological phase diagram, Dirac semimetals are of particular interest as a platform for studying topological phase transitions under external modul…
Evolution of Weyl orbit and quantum Hall effect in Dirac semimetal Cd3As2
Cheng Zhang, Awadhesh Narayan, Shiheng Lu +14
Owing to the coupling between open Fermi arcs on opposite surfaces, topological Dirac semimetals exhibit a new type of cyclotron orbit in the surface states known as Weyl orbit. He…
Enhanced Thermoelectric Properties of Dirac Semimetal Cd3As2
Tong Zhou, Cheng Zhang, Huisheng Zhang +2
We report an investigation of temperature- and doping-dependent thermoelectric behaviors of topological semimetal Cd3As2. The electrical conductivity, thermal conductivity, Seebeck…
A High-Performance Mid-infrared Optical Switch Enabled by Bulk Dirac Fermions in Cd3As2
Chunhui Zhu, Fengqiu Wang, Yafei Meng +11
Pulsed lasers operating in the 2-5 μm band are important for a wide range of applications in sensing, spectroscopy, imaging and communications. Despite recent advances with mid-inf…
Weak antilocalization in Cd3As2 thin films
Bo Zhao, Peihong Cheng, Haiyang Pan +5
Recently, it has been theoretically predicted that Cd3As2 is a three dimensional Dirac material, a new topological phase discovered after topological insulators, which exhibits a l…
Arrayed van der Waals Vertical Heterostructures based on 2D GaSe Grown by Molecular Beam Epitaxy
