Visualizing the evolution from the Mott insulator to a charge ordered insulator in lightly doped cuprates
Peng Cai, Wei Ruan, Yingying Peng +6
A central question in the high temperature cuprate superconductors is the fate of the parent Mott insulator upon charge doping. Here we use scanning tunneling microscopy to investi…
A metallic mosaic phase and the origin of Mott insulating state in 1T-TaS2
Liguo Ma, Cun Ye, Yijun Yu +8
Electron-electron and electron-phonon interactions are two major driving forces that stabilize various charge-ordered phases of matter. The intricate interplay between the two give…
Structural phase transition and electronic structure evolution in Ir1-xPtxTe2 studied by scanning tunneling microscopy
Wei Ruan, Peizhe Tang, Aifang Fang +6
The IrTe2 transition metal dichalcogenide undergoes a series of structural and electronic phase transitions when doped with Pt. The nature of each phase and the mechanism of the ph…
Single Vortex Pinning and Penetration Depth in Superconducting NdFeAsOF
Jessie T. Zhang, Jeehoon Kim, Magdalena Huefner +6
We use a magnetic force microscope (MFM) to investigate single vortex pinning and penetration depth in NdFeAsOF, one of the highest- iron-based superconductors. In…
Strong similarities between the local electronic structure of insulating iron pnictide and lightly doped cuprate
Cun Ye, Wei Ruan, Peng Cai +4
One of the major puzzles regarding unconventional superconductivity is how some of the most interesting superconductors are related to an insulating phase that lies in close proxim…
