Systematics of electronic and magnetic properties in the transition metal doped SbTe quantum anomalous Hall platform
M F. Islam, C. M. Canali, A. Pertsova +19
The quantum anomalous Hall effect (QAHE) has recently been reported to emerge in magnetically-doped topological insulators. Although its general phenomenology is well established,…
Robust spin-polarized midgap states at step edges of topological crystalline insulators
Paolo Sessi, Domenico Di Sante, Andrzej Szczerbakow +11
Topological crystalline insulators are materials in which the crystalline symmetry leads to topologically protected surface states with a chiral spin texture, rendering them potent…
Single electron gating of topological insulators
Paolo Sessi, Thomas Bathon, Konstantin A. Kokh +2
Introducing, observing, and manipulating individual impurities coupled to a host material offers the opportunity to create new device concepts based on single spin and charge state…
Impurity screening and stability of Fermi arcs against Coulomband magnetic scattering in a Weyl monopnictide
Paolo Sessi, Yan Sun, Thomas Bathon +9
We present a quasiparticle interference study of clean and Mn surface-doped TaAs, a prototypical Weyl semimetal, to test the screening properties as well as the stability of Fermi…
Dual nature of magnetic dopants and competing trends in topological insulators
Paolo Sessi, Rudro Biswas, Thomas Bathon +8
Topological insulators interacting with magnetic impurities have been reported to host several unconventional effects. These phenomena are described within the framework of gapping…
Experimental realization of a topological p-n junction by intrinsic defect-grading
T. Bathon, S. Achilli, P. Sessi +4
A junction between an n- and p-type semiconductor results in the creation of a depletion region whose properties are at the basis of nowadays electronics. If realized using topolog…
Scattering properties of the three-dimensional topological insulator Sb2Te3: Coexistence of topologically trivial and non-trivial surface states with opposite spin-momentum helicity
P. Sessi, O. Storz, T. Bathon +5
The binary chalcogenides Bi2Te3 and Bi2Se3 are the most widely studied topological insulators. Although the quantum anomalous Hall effect has recently been observed in magnetically…
Systematics of molecular self-assembled networks at topological insulators surfaces
Thomas Bathon, Paolo Sessi, Konstantin Kokh +2
The success of topological insulators (TI) in creating devices with unique functionalities is directly connected to the ability of coupling their helical spin states to well define…
Signatures of Dirac fermion-mediated magnetic order
Paolo Sessi, Felix Reis, Thomas Bathon +3
The spin-momentum locking of topological states offers an ideal platform to explore novel magneto-electric effects. These intimately depend on the ability to manipulate the spin te…
