Few-layer graphene has attracted tremendous attention owing to its exceptional electronic properties inherited from single-layer graphene and new features led by introducing extra freedoms such as interlayer stacking sequences or rotations. Effectively p
Stacking disorder will significantly modify the optical properties and interlayer coupling stretch of few-layer graphene. Here, we report the observation of the Raman breathing modes in the low-frequency range of 100–200 cm–1 in misoriented few-layer graphene on a SiO2/Si substrate. Two dominan...
These phonon interactions induce material-characteristic frequency-shifts (Stoke-shifts) in the scattered light from the illumination laser. This fingerprint region is accessible with most commercial instruments and allows valuable information to be extracted about molecules such as aromatics, carbonates, ...
The two prominent Raman modes labelled, E12g and A1g, are, respectively, the in-plane and out-of-plane phonon modes. The peak positions of the modes shift as a function of increasing layer thickness with the frequency of E12g decreasing and that of A1g increasing. Thus, the difference ...

This approach can effectively decouple phonon and carrier scattering [11], [12], [13]. The interface can effectively scatter intermediate-frequency phonons, thereby suppressing lattice thermal conductivity κL. In recent years, numerous reports have demonstrated significant reductions in lattice thermal ...

This duration is important as it influences the frequency of treatments, and how often the wound is exposed to unsterile conditions, increasing the risk of re-infection. Post-infection treatments Once an infection has formed, it can become much harder to treat and prevent more entrenched ...
