Electron-beam-induced Contactless Manipulation of Interlayer Twist in van der Waals Heterostructures
Nicola Curreli, Tero S. Kulmala, Riya Sebait +6
The ability to dynamically control the relative orientation of layers in two dimensional (2D) van der Waals (vdW) heterostructures represents a critical step toward the realization…
2μm Solid-State Laser Mode-locked By Single-Layer Graphene
A. A. Lagatsky, Z. Sun, T. S. Kulmala +9
We report a 2μm ultrafast solid-state Tm:Lu2O3 laser, mode-locked by single-layer graphene, generating transform-limited~410fs pulses, with a spectral width~11.1nm at 2067nm. The m…
Ink-Jet Printed Graphene Electronics
F. Torrisi, T. Hasan, W. Wu +9
We demonstrate ink-jet printing as a viable method for large area fabrication of graphene devices. We produce a graphene-based ink by liquid phase exfoliation of graphite in N-Meth…
Quantifying defects in graphene via Raman spectroscopy at different excitation energies
L. G. Cançado, A. Jorio, E. H. Martins Ferreira +7
We present a Raman study of Ar(+)-bombarded graphene samples with increasing ion doses. This allows us to have a controlled, increasing, amount of defects. We find that the ratio b…
