Giant Frictional Drag in Double Bilayer Graphene Heterostructures
Kayoung Lee, Jiamin Xue, David C. Dillen +3
We study the frictional drag between carriers in two bilayer graphene flakes separated by a 2 5 nm thick hexagonal boron nitride dielectric. At temperatures () lower than $\…
Band offset and negative compressibility in graphene-MoS2 heterostructures
S. Larentis, J. R. Tolsma, B. Fallahazad +4
We use electron transport to characterize monolayer graphene - multilayer MoS2 heterostructures. Our samples show ambipolar characteristics and conductivity saturation on the elect…
Chemical Potential and Quantum Hall Ferromagnetism in Bilayer Graphene
Kayoung Lee, Babak Fallahazad, Jiamin Xue +5
Bilayer graphene has a unique electronic structure influenced by a complex interplay between various degrees of freedom. We probe its chemical potential using double bilayer graphe…
Raman spectroscopy and strain mapping in individual Ge-SixGe1-x core-shell nanowires
D. C. Dillen, K. M. Varahramyan, C. M. Corbet +1
Core-shell Ge-SixGe1-x nanowires (NWs) are expected to contain large strain fields due to the lattice-mismatch at the core/shell interface. Here we report the measurement of core s…
Direct Measurement of the Fermi Energy in Graphene Using a Double Layer Structure
Seyoung Kim, Insun Jo, D. C. Dillen +5
We describe a technique which allows a direct measurement of the relative Fermi energy in an electron system using a double layer structure, where graphene is one of the two layers…
