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…
Electron optics with ballistic graphene junctions
Shaowen Chen, Zheng Han, Mirza M. Elahi +9
Electrons transmitted across a ballistic semiconductor junction undergo refraction, analogous to light rays across an optical boundary. A pn junction theoretically provides the equ…
Thermoelectric detection of propagating plasmons in graphene
Mark B. Lundeberg, Yuanda Gao, Achim Woessner +7
Controlling, detecting and generating propagating plasmons by all-electrical means is at the heart of on-chip nano-optical processing. Graphene carries long-lived plasmons that are…
Ultra-confined acoustic THz graphene plasmons revealed by photocurrent nanoscopy
Pablo Alonso-Gonzalez, Alexey Y. Nikitin, Yuanda Gao +14
Terahertz (THz) fields are widely applied for sensing, communication and quality control. In future applications, they could be efficiently confined, enhanced and manipulated - wel…
