Observation of optical absorption correlated with surface state of topological insulator
Jiwon Jeon, Kwangnam Yu, Jiho Kim +3
We performed broadband optical transmission measurements of Bi2Se3 and In-doped Bi(1-x)In(x)2Se3 thin films, where in the latter the spin-orbit coupling (SOC) strength can be tuned…
Electronic correlation determining correlated plasmons in Sb-doped BiSe
P. K. Das, T. J. Whitcher, M. Yang +15
Electronic correlation is believed to play an important role in exotic phenomena such as insulator-metal transition, colossal magneto resistance and high temperature superconductiv…
Pb-doped p-type BiSe thin films via interfacial engineering
Jisoo Moon, Zengle Huang, Weida Wu +1
Due to high density of native defects, the prototypical topological insulator (TI), BiSe, is naturally n-type. Although BiSe can be converted into p-type by substit…
Ferromagnetic Anomalous Hall Effect in Cr-doped BiSe Thin Films via Surface-State Engineering
Jisoo Moon, Jinwoong Kim, Nikesh Koirala +3
The anomalous Hall effect (AHE) is a non-linear Hall effect appearing in magnetic conductors, boosted by internal magnetism beyond what is expected from the ordinary Hall effect. W…
Gate tunable quantum Hall effects in defect-suppressed Bi2Se3 films
N. Koirala, M. Salehi, J. Moon +1
Despite many years of efforts, attempts to reach the quantum regime of topological surface states (TSS) on an electrically tunable topological insulator (TI) platform have so far f…
Quantum-Hall to Insulator Transition in Ultra-low-carrier-density Topological Insulator Films and a Hidden Phase of the Zeroth Landau Level
Maryam Salehi, Hassan Shapourian, Ilan Thomas Rosen +6
A key feature of the topological surface state under a magnetic field is the presence of the zeroth Landau level at the zero energy. Nonetheless, it has been challenging to probe t…
