Direct observation of double valence-band extrema and anisotropic effective masses of the thermoelectric material SnSe
T. Nagayama, K. Terashima, T. Wakita +14
Synchrotron-based angle-resolved photoemission spectroscopy is used to determine the electronic structure of layered SnSe, which was recently turned out to be a potential thermoele…
Observation of Zero Resistance in As-Electrodeposited FeSe
Aichi Yamashita, Ryo Matsumoto, Masashi Tanaka +5
Superconducting FeSe films were electrochemically deposited on rolling-assisted biaxially textured substrate (RABiTS) tape. We observed zero resistivity in the as-electrodeposited…
Electronic Transport Properties of Carrier Controlled SnSe Single Crystals
Aichi Yamashita, Osamu Ogiso, Ryo Matsumoto +6
We found that the electronic transport property of SnSe single crystals was sensitive to oxygen content. Semiconducting SnSe single crystals were obtained by using Sn of grain form…
The influence of the in-plane lattice constant on the superconducting transition temperature of FeSe0.7Te0.3 thin films
Feifei Yuan, Kazumasa Iida, Vadim Grinenko +12
Epitaxial Fe(Se,Te) thin films were prepared by pulsed laser deposition on (La0.18Sr0.82)(Al0.59Ta0.41)O3 (LSAT), CaF2-buffered LSAT and bare CaF2 substrates, which exhibit an almo…
Phase Diagram of FeSe Deposited by Electrochemical Technique with Different Temperature and Voltage
Aichi Yamashita, Masashi Tanaka, Hiroyuki Takeya +1
High-quality crystalline FeSe is successfully synthesized in 5 minutes by an electrochemical deposition technique via increasing the solution temperature. The synthesis of FeSe hav…
Phase-separation control of KFeSe superconductor through rapid-quenching process
Yusuke Yanagisawa, Masashi Tanaka, Aichi Yamashita +5
KFeSe exhibits an iron-vacancy ordering at C and separates into two phases: a minor superconducting (iron-vacancy-disordered) phase and a majo…
