Imaging ambipolar two-dimensional carriers induced by the spontaneous electric polarization of a polar semiconductor BiTeI
Y. Kohsaka, M. Kanou, H. Takagi +2
Two-dimensional (2D) mobile carriers are a wellspring of quantum phenomena. Among various 2D-carrier systems, such as field effect transistors and heterostructures, polar materials…
Unusual oxygen isotope effects in cuprates -- importance of doping
G. -H. Gweon, T. Sasagawa, H. Takagi +2
A recent angle resolved photoelectron spectroscopy (ARPES) study by Douglas et al. \cite {dessau-comment} on oxygen isotope exchanged Bi_2Sr_2CaCu_2O superconductors report…
Angle-resolved photoemission studies of lattice polaron formation in the cuprate Ca2CuO2Cl2
K. M. Shen, F. Ronning, W. Meevasana +10
To elucidate the nature of the single-particle excitations in the undoped parent cuprates, we have performed a detailed study of Ca2CuO2Cl2 using photoemission spectroscopy. The ph…
Strong and complex electron-lattice correlation in optimally doped BiSrCaCuO
G. -H. Gweon, S. Y. Zhou, M. C. Watson +3
We discuss the nature of electron-lattice interaction in optimally doped BiSrCaCuO samples, using isotope effect (IE) in angle resolved photoemission spectrosco…
Imaging nano-scale electronic inhomogeneity in lightly doped Mott insulator Ca_{2-x}Na_{x}CuO_{2}Cl_{2}
Y. Kohsaka, K. Iwaya, S. Satow +4
The spatial variation of electronic states was imaged in the lightly doped Mott insulator Ca_{2-x}Na_{x}CuO_{2}Cl_{2} using scanning tunneling microscopy / spectroscopy (STM/STS).…
Evolution of a Metal to Insulator Transition in CaNaCuOCl, as seen by ARPES
F. Ronning, T. Sasagawa, Y. Kohsaka +10
We present angle resolved photoemission (ARPES) data on Na-doped CaCuOCl. We demonstrate that the chemical potential shifts upon doping the system across the insulator…
