Magneto-Thermoelectric Transport in Graphene Quantum Dot with Strong Correlations
Laurel E. Anderson, Antti Laitinen, Andrew Zimmerman +7
Disorder at the etched edges of graphene quantum dots (GQD) enables random all-to-all interactions between localized charges in partially-filled Landau levels, providing a potentia…
Electron-phonon coupling in copper intercalated BiSe
Maciej Wiesner, Kristie Koski, Antti Laitinen +3
We report charge and heat transport studies in copper-intercalated topological insulator BiSe hybrid devices. Measured conductivity shows impact of quantum corrections, ele…
Suppression of noise in graphene due to non-scalar mobility fluctuations induced by impurity motion
Masahiro Kamada, Weijun Zeng, Antti Laitinen +5
Low frequency resistance variations due to mobility fluctuations is one of the key factors of noise in metallic conductors. According to theory, such noise in a two-dimension…
De Haas-van Alphen effect in graphene
Juuso Manninen, Antti Laitinen, Francesco Massel +1
In our work, we study the dynamics of a graphene Corbino disk supported by a gold mechanical resonator in the presence of a magnetic field. We demonstrate here that our graphene/go…
Electrical low-frequency noise due to surface diffusion of scatterers on an ultra low noise graphene platform
Masahiro Kamada, Antti Laitinen, Weijun Zeng +5
Low-frequency noise is ubiquitous, even in high-end electronic devices. For qubits such noise results in decrease of their coherence times. Recently, it was found that adso…
Strong magnetoresistance in a graphene Corbino disk at low magnetic fields
Masahiro Kamada, Vanessa Gall, Jayanta Sarkar +4
We have measured magnetoresistance of suspended graphene in the Corbino geometry at magnetic fields up to T, i.e., in a regime uninfluenced by Shubnikov-de Haas oscillati…
