Room-Temperature Superconductivity in Boron-Nitrogen Doped Lanthanum Superhydride
Yanfeng Ge, Fan Zhang, Russell J. Hemley
Recent theoretical and experimental studies of hydrogen-rich materials at megabar pressures (i.e., >100 GPa) have led to the discovery of very high-temperature superconductivity in…
Strong mid-infrared photoresponse in small-twist-angle bilayer graphene
Bingchen Deng, Chao Ma, Qiyue Wang +5
Recently the small-twist-angle (< 2°) bilayer graphene has received extraordinary attentions due to its exciting physical properties. Compared with monolayer graphene, the Brilloui…
Hole-Doped Room-Temperature Superconductivity in HSZ (Z=C, Si)
Yanfeng Ge, Fan Zhang, Ranga P. Dias +2
We examine the effects of the low-level substitution of S atoms by C and Si atoms on the superconductivity of HS with the structure at megabar pressure. The hole d…
Higher-order Dirac sonic crystals
Huahui Qiu, Meng Xiao, Fan Zhang +1
Discovering new topological phases of matter is a major theme in fundamental physics and materials science. Dirac semimetal provides an exceptional platform for exploring topologic…
Quasi-One-Dimensional Higher-Order Topological Insulators
Chiho Yoon, Cheng-Cheng Liu, Hongki Min +1
Quasi-1D materials BiX (X=Br,I) are prototype weak topological insulators (TI) in the phase. For the phases, recent high-throughput database screening suggests…
Inelastic electron tunneling in 2H-TaNbSe evidenced by scanning tunneling spectroscopy
Xing-Yuan Hou, Fan Zhang, Xin-Hai Tu +12
We report a detailed study of tunneling spectra measured on 2H-TaNbSe () single crystals using a low-temperature scanning tunneling microscope. The pro…
