Enhancement of superconductivity and its relation to lattice expansion in InTe
M. Kriener, M. S. Bahramy, Y. Tokura +1
The quest to govern the driving forces behind superconductivity and gain control over the superconducting transition temperature is as old as the phenomenon itself. Microsc…
Evolution of electronic states and emergence of superconductivity in the polar semiconductor GeTe by doping valence-skipping In
M. Kriener, M. Sakano, M. Kamitani +7
GeTe is a chemically simple IV-VI semiconductor which bears a rich plethora of different physical properties induced by doping and external stimuli. These include, among others, fe…
Unconventional Superconductivity in electron-doped layered metal nitride halides N ( = Ti, Zr, Hf; = Cl, Br, I)
Yuichi Kasahara, Kazuhiko Kuroki, Shoji Yamanaka +1
In this review, we present a comprehensive overview of superconductivity in electron-doped metal nitride halides N ( = Ti, Zr, Hf; = Cl, Br, I) with layered crystal st…
Strong Suppression of Coherence Effect and Appearance of Pseudogap in Layered Nitride Superconductor Li_xZrNCl: ^91Zr- and ^15N- NMR Studies
Hisashi Kotegawa, Satoru Oshiro, Yuki Shimizu +5
We present NMR measurements of the layered nitride superconductor Li_xZrNCl. The nuclear spin-lattice relaxation rate, 1/T_1, shows that the coherence peak is strongly suppressed i…
Fully Gapped Single-Particle Excitations in the Lightly Doped Cuprates
K. M. Shen, T. Yoshida, D. H. Lu +23
The low-energy excitations of the lightly doped cuprates were studied by angle-resolved photoemission spectroscopy. A finite gap was measured over the entire Brillouin zone, includ…
An angle-resolved photoemission spectral function analysis of the electron doped cuprate Nd_1.85Ce_0.15CuO_4
N. P. Armitage, D. H. Lu, C. Kim +15
Using methods made possible by recent advances in photoemission technology, we perform an indepth line-shape analysis of the angle-resolved photoemission spectra of the electron do…
