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…
Dirac fermion reflector by ballistic graphene sawtooth-shaped npn junctions
Sei Morikawa, Quentin Wilmart, Satoru Masubuchi +4
We have realized a Dirac fermion reflector in graphene by controlling the ballistic carrier trajectory in a sawtooth-shaped npn junction. When the carrier density in the inner p-re…
A graphene Zener-Klein transistor cooled by a hyperbolic substrate
W. Yang, S. Berthou, X. Lu +11
Engineering of cooling mechanisms is a bottleneck in nanoelectronics. Whereas thermal exchanges in diffusive graphene are mostly driven by defect assisted acoustic phonon scatterin…
