Exact continuum theory of anti-Klein tunneling in bilayer graphene
P. A. Maksym, H. Aoki
Exact conditions for anti-Klein transmission zeros are found analytically with a 4-component continuum approach which includes trigonal warping. Anti-Klein tunneling occurs at obli…
Complete Spin and Valley Polarization by Total External Reflection from Potential Barriers in Bilayer Graphene and Monolayer Transition Metal Dichalcogenides
P. A. Maksym, H. Aoki
It is shown that potential barriers in bilayer graphene (BLG) and monolayer transition metal dichalcogenides (TMDs) can split a valley unpolarized incident current into reflected a…
Probing the local electronic structure of isovalent Bi atoms in InP
C. M. Krammel, A. R. da Cruz, M. E. Flatté +7
Cross-sectional scanning tunneling microscopy (X-STM) is used to experimentally study the influence of isovalent Bi atoms on the electronic structure of InP. We map the spatial pat…
Magnetic field controlled vacuum charge in graphene quantum dots with a mass gap
P. A. Maksym, H. Aoki
The effect of a magnetic field on the charged vacuum is investigated. The field dependence of the energy levels causes jumps in the total vacuum charge that occur whenever an energ…
Unraveling quantum Hall breakdown in bilayer graphene with scanning gate microscopy
M. R. Connolly, R. K. Puddy, D. Logoteta +7
We use low-temperature scanning gate microscopy (SGM) to investigate the breakdown of the quantum Hall regime in an exfoliated bilayer graphene flake. SGM images captured during br…
Reading and writing charge on graphene devices
M. R. Connolly, E. D. Herbschleb, R. K. Puddy +5
We use a combination of charge writing and scanning gate microscopy to map and modify the local charge neutrality point of graphene field-effect devices. We give a demonstration of…
