Raman spectra of twisted bilayer graphene close to the magic angle
Tiago C. Barbosa, Andreij C. Gadelha, Douglas A. A. Ohlberg +5
In this work, we study the Raman spectra of twisted bilayer graphene samples as a function of their twist-angles (), ranging from 0.03 to 3.40, where local a…
The limits of Near Field Immersion Microwave Microscopy evaluated by imaging bilayer graphene Moiré patterns
Douglas A. A. Ohlberg, Diego Tami, Andreij C. Gadelha +11
Molecular and atomic imaging required the development of electron and scanning probe microscopies to surpass the physical limits dictated by diffraction. Nano-infrared experiments…
Lattice dynamics localization in low-angle twisted bilayer graphene
Andreij C. Gadelha, Douglas A. A. Ohlberg, Cassiano Rabelo +20
A low twist angle between the two stacked crystal networks in bilayer graphene enables self-organized lattice reconstruction with the formation of a periodic domain. This superlatt…
Monolayer Molybdenum Disulfide Nanoribbons with High Optical Anisotropy
Jiang-Bin Wu, Huan Zhao, Yuanrui Li +5
Two-dimensional Molybdenum Disulfide (MoS2) has shown promising prospects for the next generation electronics and optoelectronics devices. The monolayer MoS2 can be patterned into…
Quantum Conductance Oscillations in Metal/Molecule/Metal Switches at Room Temperature
Feng Miao, Douglas Ohlberg, Duncan Stewart +2
Conductance switching has been reported in many molecular junction devices, but in most cases has not been convincingly explained. We investigate conductance switching in Pt/steari…
