Revealing electrically undetectable room temperature surface-mobility of bulky topological insulators by spectroscopic techniques
Bumjoo Lee, Jinsu Kim, Jonghyeon Kim +11
High surface-mobility, which is attributable to topological protection, is a trademark of three-dimensional topological insulators (3DTIs). Exploiting surface-mobility indicates su…
Extremely high mobility over 5000 cm2/Vs obtained from MoS2 nanosheet transistor with NiOx Schottky gate
Hee Sung Lee, Seung Su Baik, Sung-Wook Min +7
Molybdenum disulfide (MoS2) nanosheet, one of two dimensional (2D) semiconductors, has recently been regarded as a promising material to break through the limit of present semicond…
Formation of mid-gap states and ferromagnetism in semiconducting CaB
Jong-Soo Rhyee, B. H. Oh, B. K. Cho +5
We present a consistent overall picture of the electronic structure and ferromagnetic interaction in CaB, based on our joint transport, optical, and tunneling measurements on h…
Electronic and Magnetic Properties of Electron-doped Superconductor, Sm_{1.85}Ce_{0.15}CuO_{4-delta}
B. K. Cho, Jae Hoon Kim, Young Jin Kim +3
Temperature-dependent magnetization (M(T)) and specific heat (C_p(T)) measurements were carried out on single crystal Sm_{1.85}Ce_{0.15}CuO_{4-delta} (T_c = 16.5 K). The magnetic a…
Grazing Incidence Infrared Reflectivity of LaSrCuO and NbN
H. S. Somal, B. J. Feenstra, J. Schützmann +7
Infrared reflectivity measurements, using p-polarized light at a grazing angle of incidence, show an increased sensitivity to the optical conductivity of highly reflecting supercon…
In-Plane and Out-of-Plane Charge Dynamics of High- Cuprates
Dirk van der Marel, Jae H. Kim
We propose a theoretical expression for the - and -dependent dielectric function of a stack of two-dimensional layers coupled along the direction perpendicular to the layers,…
Damping mechanism for the strongly renormalized -axis charge transport in high- cuprate superconductors
Jae H. Kim, H. S. Somal, D. van der Marel
We analyze the -axis infrared reflectivity of LaSrCuO single crystals. The plasma edge near 6 meV, observed below , is due to Cooper-pair tunneling. T…
