Quantum electron liquid and its possible phase transition
Sunghun Kim, Joonho Bang, Chan-young Lim +14
Purely quantum electron systems exhibit intriguing correlated electronic phases by virtue of quantum fluctuations in addition to electron-electron interactions. To realize such qua…
Study of Yu-Shiba-Rusinov bound states by tuning the electron density at the Fermi energy
Sang Yong Song, Yoon Sung Park, Yongchan Jeong +3
Magnetic atoms can break the Cooper pairs of superconductors, leading to the formation of Yu-Shiba-Rusinov (YSR) bound states inside superconducting gaps. Theory predicts that the…
Controllable pn junctions in threedimensional Dirac semimetal CdAs nanowires
Janice Ruth Bayogan, Kidong Park, Zhuo Bin Siu +11
We demonstrate a controllable pn junction in a threedimensional Dirac semimetal (DSM) CdAs nanowire with two recessed bottom gates. The device exhibits four different…
Visualization of local magnetic moments emerging from impurities in the Hund's metal states of FeSe
Sang Yong Song, J. H. J. Martiny, A. Kreisel +2
Understanding the origin of the magnetism of high temperature superconductors is crucial for establishing their unconventional pairing mechanism. Recently, theory predicts that FeS…
Quantum dots formed in three-dimensional Dirac semimetal CdAs nanowires
Minkyung Jung, Kenji Yoshida, Kidong Park +9
We demonstrate quantum dot (QD) formation in three-dimensional Dirac semimetal CdAs nanowires using two electrostatically tuned pn junctions with a gate and magnetic…
Surface reconstruction and charge modulation in BaFe2As2 superconducting film
S. Kim, S. Yi, M. Oh +13
Whether or not epitaxially grown superconducting films have the same bulk-like superconducting properties is an important concern. We report the structure and the electronic proper…
