In this paper, the experimental and theoretical results that may give an insight into the
current status and possible prospects of the family of (sp1+ sp2) hybridized carbon …

The mechanical behavior of high quality two-dimensional (2D) crystals offers exciting
opportunities for new material design, such as the combination of extremely high in-plane …

Inorganic semiconductors are vital for a number of critical applications but are almost
universally brittle. Here, we report the superplastic deformability of indium selenide (InSe) …

Wavelike thermal transport in solids, referred to as second sound, is an exotic phenomenon
previously limited to a handful of materials at low temperatures. The rare occurrence of this …

We present an equation of state (EOS) that describes how the hydrostatic change in surface
area is related to two-dimensional in-plane pressure (F) and yields the measure of a …

Most of the studied two-dimensional (2D) materials are based on highly symmetric
hexagonal structural motifs. In contrast, lower-symmetry structures may have exciting …

We uncover the constitutive relation of graphene and probe the physics of its optical
phonons by studying its Raman spectrum as a function of uniaxial strain. We find that the …

The quest for materials capable of realizing the next generation of electronic and photonic
devices continues to fuel research on the electronic, optical and vibrational properties of …

Ever since the isolation of single-layer graphene in 2004, two-dimensional layered
structures have been among the most extensively studied classes of materials. To date, the …

This paper presents a comparative study of the lattice dynamics of three-dimensional
layered MoS2 and two-dimensional single layer MoS2 based on the density functional …
