TL;DR: In this article, a contamination-free, one-step and universal Au-assisted mechanical exfoliation method was proposed to isolate 40 types of single-crystalline monolayers, including elemental two-dimensional crystals, metal-dichalcogenides, magnets and superconductors.

TL;DR: A one-step, contamination-free, Au-assisted mechanical exfoliation method for 2D materials, and isolate 40 types of single-crystalline monolayers, including elemental 2D crystals, metal-dichalcogenides, magnets and superconductors with millimetre size is developed.

TL;DR: In this paper, the temperature-dependent Raman frequency shift of suspended graphene was similar as that of supported graphene, which indicated that the strain caused by thermal expansion coefficient mismatch between graphene and substrate cannot be neglected from suspended graphene, and thus a semi-quantitative factor was introduced to estimate the contribution from substrate to the suspended graphene.

TL;DR: New hierarchical few-layer graphene nanostructure provides a feasible strategy to understand the ultra-adhesive mechanism of the “gecko effect’ or “rose effect” and enhance the wettability of graphene for many practical applications.

TL;DR: In this article, the thermal expansion coefficient of few-layer MoS2, suspended and supported materials were systematically investigated using Raman spectroscopy in the temperature range from 77 to 557 K. The temperature-dependent evolution of the Raman frequency shift for suspended materials exhibited prominent differences from that for supported materials.
