Ramanh-BNLiquid crystalAdditiveThe h-BN nanosheets (h-BNn) was used as an additive to 4-n-pentyl-4'-cyanobiphyl liquid crystal (5CB), and its influence on tribological performance was investigated on a ball-on-disc tribometer for steel/steel contacts. Micron h-BN (h-BN mu) was used ...
Raman spectrum (532nm) collected from h-BN solutions Frequently asked questions Q1: Are these solutions good for catalytic measurements? A: Yes, our 2D solutions are commonly used by catalysis community Q2: What is the volume of the solution?

Raman mapping was performed in a 10 μm × 10 μm region with a step size of 0.2 μm. The absorption spectra were investigated using ultraviolet–visible–infrared spectroscopy (Cary 5000 ultraviolet–visible– near-infrared, Agilent Technologies, Santa Clara, CA, USA). The h-BN films ...

However, Raman-active phonons are limited to a few vibration modes due to stringent optical selection rules. Inelastic electron tunneling spectroscopy (IETS) has proven its capability in probing phonon excitations without selection rule limitations7–9. Initial IETS studies on graphene devices with ...
which eventually lead to large h-BN crystals. After a careful purification of the recovered products, h-BN crystals with 6N in purity can be achieved. The high quality of the final product can be manifested by sharp Raman spectra, excellent diffraction pattern, and easy exfoliation characteristics...
The Raman spectrum of monolayer CVD graphene27 on SiO2/Si substrate show the G and 2D peaks at 1597 cm−1 and 2652 cm−1 respectively28 with a small D peak (see Supplementary Fig. S1a). The grain size of the CVD graphene is mostly between 1–5 µm range. The Raman ...
we measured the Raman spectra of the heterostructures after they were transferred onto a SiO2/Si substrate. The red and blue lines in Fig.1cshow the corresponding Raman spectra of the graphene (G, 2D peaks) and h-BN (E2gpeak), respectively. Notably, the Raman mapping image (Fig.1e) in...
