Direct evidence of Klein-antiKlein tunneling of graphitic electrons in a Corbino geometry
Mirza M. Elahi, Yihang Zeng, Cory R. Dean +1
Transport measurement of electron optics in monolayer graphene p-n junction devices has been traditionally studied with negative refraction and chiral transmission experiments in H…
Thermal conductivity measurements of sub-surface buried substrates by steady-state thermoreflectance
Md Shafkat Bin Hoque, Yee Rui Koh, Kiumars Aryana +10
Measuring the thermal conductivity of sub-surface buried substrates are of significant practical interests. However, this remains challenging with traditional pump-probe spectrosco…
Impact of geometry and non-idealities on electron 'optics' based graphene p-n junction devices
Mirza M. Elahi, K. M. Masum Habib, Ke Wang +3
We articulate the challenges and opportunities of unconventional devices using the photon like flow of electrons in graphene, such as Graphene Klein Tunnel (GKT) transistors. The u…
Atomic scale characterization of graphene p-n junctions for electron-optical applications
Xiaodong Zhou, Alexander Kerelsky, Mirza M. Elahi +8
Graphene p-n junctions offer a potentially powerful approach towards controlling electron trajectories via collimation and focusing in ballistic solid-state devices. The ability of…
Graphene Transistor Based on Tunable Dirac-Fermion-Optics
Ke Wang, Mirza M. Elahi, K. M. Masum Habib +5
The linear energy-momentum dispersion, coupled with pseudo-spinors, makes graphene an ideal solid-state material platform to realize an electronic device based on Dirac-Fermionic r…
Graphene Klein tunnel transistors for high speed analog RF applications
Yaohua Tan, Mirza M. Elahi, Han-Yu Tsao +3
We propose Graphene Klein tunnel transistors (GKTFET) as a way to enforce current saturation while maintaining large mobility for high speed radio frequency (RF) applications. The…
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…
