Nanoscale interplay of strain and doping in a high-temperature superconductor
Ilija Zeljkovic, Jouko Nieminen, Dennis Huang +10
The highest temperature superconductors are electronically inhomogeneous at the nanoscale, suggesting the existence of a local variable which could be harnessed to enhance the supe…
Observation of Quantum-Tunneling Modulated Spin Texture in Ultrathin Topological Insulator Bi2Se3 Films
Madhab Neupane, Anthony Richardella, Jaime Sánchez-Barriga +18
Understanding the spin-texture behavior of boundary modes in ultrathin topological insulator films is critically essential for the design and fabrication of functional nano-devices…
Non-Kondo-like Electronic Structure in the Correlated Rare-Earth Hexaboride YbB
Madhab Neupane, Su-Yang Xu, Nasser Alidoust +11
We present angle-resolved photoemission studies on the rare-earth hexaboride YbB, which has recently been predicted to be a topological Kondo insulator. Our data do not agree w…
Spin correlated electronic state on the surface of a spin-orbit Mott system (Layered Iridates)
Chang Liu, Su-Yang Xu, Nasser Alidoust +13
Novel phases of two dimensional electron systems resulting from new surface or interface modified electronic structures have generated significant interest in material science. We…
Direct observation of the transition from indirect to direct bandgap in atomically thin epitaxial MoSe2
Yi Zhang, Tay-Rong Chang, Bo Zhou +13
Quantum systems in confined geometries are host to novel physical phenomena. Examples include quantum Hall systems in semiconductors and Dirac electrons in graphene. Interest in su…
