Frictional magneto-Coulomb drag in graphene double-layer heterostructure
Xiaomeng Liu, Lei Wang, Kin Chung Fong +7
Coulomb interaction between two closely spaced parallel layers of electron system can generate the frictional drag effect by interlayer Coulomb scattering. Employing graphene doubl…
SU-8 clamped CVD graphene drum resonators
Sunwoo Lee, Changyao Chen, Vikram V. Deshpande +8
Graphene mechanical resonators are the ultimate two-dimensional nanoelectromechanical systems (NEMS) with applications in sensing and signal processing. While initial devices have…
Modulation of mechanical resonance by chemical potential oscillation in graphene
Changyao Chen, Vikram V. Deshpande, Mikito Koshino +5
The classical picture of the force on a capacitor assumes a large density of electronic states, such that the electrochemical potential of charges added to the capacitor is given b…
Coulomb drag between carbon nanotube and graphene
Jean-Damien Pillet, Austin Cheng, Takashi Taniguchi +2
We report the observation of Coulomb drag between a two-dimensional (2D) electron gas in graphene and a one-dimensional (1D) wire composed of a carbon nanotube. We find that drag o…
Landau level evolution driven by band hybridization in mirror symmetry broken ABA-stacked trilayer graphene
Yuya Shimazaki, Toru Yoshizawa, Ivan V. Borzenets +7
Layer stacking and crystal lattice symmetry play important roles in the band structure and the Landau levels of multilayer graphene. ABA-stacked trilayer graphene possesses mirror-…
Engineering Quantum Confinement in Semiconducting van der Waals Heterostructure
Ke Wang, Takashi Taniguchi, Kenji Watanabe +1
Spatial confinement and manipulation of charged carriers in semiconducting nanostructures are essential for realizing quantum electronic devices. Gate-defined nanostructures made o…
