Fully two-dimensional incommensurate charge modulation on the Pd-terminated polar surface of PdCoO2
Pengfei Kong, Guowei Li, Zhongzheng Yang +4
Here we use low-temperature scanning tunneling microscopy and spectroscopy to study the polar surfaces of PdCoO2. On the CoO2-terminated polar surface, we detect the quasiparticle…
Inducing and tuning Kondo screening in a narrow-electronic-band system
Shiwei Shen, Chenhaoping Wen, Pengfei Kong +7
Although the single-impurity Kondo physics has already been well understood, the understanding of the Kondo lattice problem where a dense array of local moments couples to the cond…
Charge density wave orders and enhanced superconductivity under pressure in the kagome metal CsV3Sb5
Qi Wang, Pengfei Kong, Wujun Shi +12
Superconductivity in topological kagome metals has recently received great research interests. Here, charge density wave (CDW) orders and the evolution of superconductivity under v…
Roles of the Narrow Electronic Band near the Fermi Level in 1T-TaS-Related Layered Materials
Chenhaoping Wen, Jingjing Gao, Yuan Xie +9
Here we use low-temperature scanning tunneling microscopy and spectroscopy (STM/STS) to reveal the roles of the narrow electronic band in two 1T-TaS-related materials (bulk 1T-…
