Microscopic mechanism of van der Waals heteroepitaxy in the formation of MoS2/hBN vertical heterostructures
Mitsuhiro Okada, Mina Maruyama, Susumu Okada +9
Recent works have revealed that van der Waals (vdW) epitaxial growth of 2D materials on crystalline substrates, such as hexagonal boron nitride (hBN), leads to formation of self-al…
Geometrically Enhanced Thermoelectric Effects in Graphene Nanoconstrictions
Achim Harzheim, Jean Spiece, Charalambos Evangeli +8
The influence of nanostructuring and quantum confinement on the thermoelectric properties of materials has been extensively studied. While this has made possible multiple breakthro…
Field-Effect Control of Graphene-Fullerene Thermoelectric Nanodevices
Pascal Gehring, Achim Harzheim, Jean Spièce +10
Although it was demonstrated that discrete molecular levels determine the sign and magnitude of the thermoelectric effect in single-molecule junctions, full electrostatic control o…
Quantum Interference in Graphene Nanoconstrictions
Pascal Gehring, Hatef Sadeghi, Sara Sangtarash +7
We report quantum interference effects in the electrical conductance of chemical vapor deposited graphene nanoconstrictions fabricated using feedback controlled electroburning. The…
Electrically tunable organic-inorganic hybrid polaritons with monolayer WS2
Lucas C. Flatten, David M. Coles, Zhengyu He +4
Exciton-polaritons are quasiparticles consisting of a linear superposition of photonic and excitonic states, offering potential for nonlinear optical devices. The excitonic compone…
Resonant optomechanics with a vibrating carbon nanotube and a radio-frequency cavity
Natalia Ares, Tian Pei, Aquila Mavalankar +4
In an optomechanical setup, the coupling between cavity and resonator can be increased by tuning them to the same frequency. We study this interaction between a carbon nanotube res…
