Raman spectroscopy is now an extremely important technique for the analysis of carbon-
based materials. It is demonstrated how it can be used to give a unique insight into …

Graphene-based materials exhibit remarkable electronic, optical, and mechanical
properties, which has resulted in both high scientific interest and huge potential for a variety …

Raman spectroscopy is one of the most useful tools for the analysis of two-dimensional (2D)
materials. While MXenes are a very large family of 2D transition metal carbides and nitrides …

Twisted bilayer graphene (tBLG) has recently attracted growing interest due to its unique
twist-angle-dependent electronic properties. The preparation of high-quality large-area …

In this review, we survey the recent advances in nonlinear optics and the applications of two-
dimensional (2D) materials. We briefly cover the key developments pertaining to research in …

This article reviews the theoretical and experimental work related to the electronic properties
of bilayer graphene systems. Three types of bilayer stackings are discussed: the AA, AB, and …

Van der Waals coupling is emerging as a powerful method to engineer physical properties
of atomically thin two-dimensional materials. In coupled graphene–graphene and graphene …

Quantum states of quasiparticles in solids are dictated by symmetry. We have experimentally
demonstrated quantum states of Dirac electrons in a two-dimensional quasicrystal without …

Optical second harmonic generation (SHG) is known as a sensitive probe to the crystalline
symmetry of few-layer transition metal dichalcogenides (TMDs). Layer-number dependent …
