Extracting single electron wavefunctions from a quantum electrical current
A. Marguerite, B. Roussel, R. Bisognin +10
Quantum nanoelectronics has entered an era where quantum electrical currents are built from single to few on-demand elementary excitations. To date however, very limited tools have…
RF-quantum capacitance of the topological insulator Bi2Se3 in the bulk depleted regime for field-effect transistors
A. Inhofer, J. Duffy, M. Boukhicha +9
A Metal-dielectric-topological insulator capacitor device based on hBN-encapsulated CVD grown Bi2Se3 is realized and investigated in the radio frequency regime. The RF quantum capa…
Volkov-Pankratov states in topological heterojunctions
S. Tchoumakov, V. Jouffrey, A. Inhofer +4
We show that a smooth interface between two insulators of opposite topological Z2 indices possesses multiple surface states, both massless and massive. While the massless surface s…
Observation of Volkov-Pankratov states in topological HgTe heterojunctions using high-frequency compressibility
A. Inhofer, S. Tchoumakov, B. A. Assaf +13
It is well established that topological insulators sustain Dirac fermion surface states as a consequence of band inversion in the bulk. These states have a helical spin polarizatio…
Josephson junction dynamics in the presence of - and -periodic supercurrents
F. Domínguez, O. Kashuba, E. Bocquillon +7
We investigate theoretically the dynamics of a Josephson junction in the framework of the RSJ model. We consider a junction that hosts two supercurrrent contributions: a - and…
Dynamical transport measurement of the Luttinger parameter in helical edges states of 2D topological insulators
Tobias Müller, Ronny Thomale, Björn Trauzettel +2
One-dimensional (1D) electron systems in the presence of Coulomb interaction are described by Luttinger liquid theory. The strength of Coulomb interaction in the Luttinger liquid,…
