Evidences for the exciton gas phase and its condensation in monolayer 1T-ZrTe2
Yekai Song, Chunjing Jia, Hongyu Xiong +15
The excitonic insulator (EI) is a Bose-Einstein condensation (BEC) of excitons bound by electron-hole interaction in a solid, which could support high-temperature BEC transition. T…
Electron-plasmon interaction induced plasmonic-polaron band replication in epitaxial perovskite SrIrO films
Zhengtai Liu, Wanling Liu, Ruixiang Zhou +12
Electron-boson interaction is fundamental to a thorough understanding of various exotic properties emerging in many-body physics. In photoemission spectroscopy, photoelectron emiss…
Epitaxial growth and characterization of high quality Bi2O2Se thin films on SrTiO3 substrates by pulsed laser deposition
Yekai Song, Zhuojun Li, Hui Li +8
Recently, Bi2O2Se is discovered as a promising two-dimensional (2D) semiconductor for next generation electronics, due to its moderate bandgap size, high electron mobility and pron…
Single-crystal growth and extremely high H_c2 of 12442-type Fe-based superconductor KCa_2Fe_4As_4F_2
Teng Wang, Jianan Chu, Hua Jin +11
Millimeter sized single crystals of KCa_2Fe_4As_4F_2 were grown using a self-flux method. The chemical compositions and crystal structure were characterized carefully. Superconduct…
Unveiling the Charge Density Wave Inhomogeneity and Pseudogap State in 1T-TiSe2
Kai-Wen Zhang, Chao-Long Yang, Bin Lei +8
By using scanning tunneling microscopy (STM) / spectroscopy (STS), we systematically characterize the electronic structure of lightly doped 1T-TiSe2, and demonstrate the existence…
