Single Layer Materials

It's slow and inefficient, but the semiconductor is only one molecule thick.

Scientists found quantum edge states in ultracold sodium atoms, possibly leading to highly efficient energy systems with minimal loss.

MIT physicists and colleagues report new insights into exotic particles key to a form of magnetism that has attracted growing interest because it originates from ultrathin materials only a few atomic layers thick.

Surface-enhanced Raman scattering (SERS) is a powerful fingerprint analysis and detection technique that plays an important role in the fields of food safety, environmental protection, bio-imaging and hazardous substance identification. Electromagnetic enhancement (EM) and chemical enhancement (CM) are the two recognized mechanisms of action for amplifying Raman signals.

The Quantum Systems Accelerator (QSA) pioneers studies to build and co-design the next generation of programmable quantum devices. An interdisciplinary team of scientists from QSA institutions, Lawrence Berkeley National Laboratory (Berkeley Lab), and the University of California, Berkeley (UC Berkeley), in collaboration with Los Alamos National Laboratory, conducted a series of experiments with a new type of…

Hyperspectral imaging uses the full spectrum of light to give detailed insights on nature and its behavior. These insights open a realm for manifold applications, including autonomous driving, environmental monitoring, health care, space exploration or even agriculture and food processing.

National University of Singapore (NUS) physicists have developed a technique to precisely control the alignment of supermoiré lattices by using a set of golden rules, paving the way for the advancement of next generation moiré quantum matter.

Two-dimensional transition-metal dichalcogenides (2D TMDs), especially MoS2, are at the forefront of new-generation 2D materials, and industrial-level efforts are being made to produce them at a large scale with reasonable performance for electronic device applications. Usually, for display applications, charge carrier mobility of 2 cm2/V.s is sufficient.

The next generation of 2D semiconductor materials doesn't like what it sees when it looks in the mirror. Current synthesizing approaches to make single-layer nanosheets of semiconducting material for atomically thin electronics develop a peculiar "mirror twin" defect when the material is deposited on single-crystal substrates like sapphire. The synthesized nanosheet contains grain boundaries that act as a mirror,…

A Chinese team has published new work in Energy Material Advances.

A team of Clemson University chemists has constructed a novel two-dimensional electrically conductive metal-organic framework (MOF), a breakthrough that could help advance modern electronics and energy technologies.

Ever since the discovery of the two-dimensional form of graphite (called graphene) almost twenty years ago, interest in 2D materials and their special physical properties has skyrocketed. Famously, graphene was produced by exfoliating bulk graphite using sticky tape. Although it was good enough for a Nobel Prize, this method has its drawbacks.

2D materials get their strength from their atom-thin, sheet like structure. However, stacking multiple layers of a 2D material will sap it of the qualities that make it so useful.

Cambridge researchers have discovered a new topological phase in a two-dimensional system, which could be used as a new platform for exploring topological physics in nanoscale devices.

Two-dimensional monolayer nanosheets made from layered perovskite have many desirable properties. However, it has been difficult to create them with tunable bandgaps in the visible region without adding oxygen defects. Recently, researchers from Japan were able to successfully develop chemically stable nanosheets from perovskite oxynitrides which had controllable bandgaps. These nanosheets have immense potential…

Prof. Liu Lei's group from Peking University, users of the Steady-state High Magnetic Field Experimental Facility (SHMFF), Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences, together with Prof. Wang Zhaosheng from HFIPS and other collaborators, revealed the structure-property relationship in two-dimensional (2D) amorphous materials for the first time by studying amorphous monolayer…

New material reduces pressures needed more than a hundredfold, but experts urge caution over structural questions and previously retracted research

Physicists at the University of Wisconsin-Madison have directly measured the fluid-like flow of electrons in graphene at nanometer resolution for the first time. The results appear in the journal Science today.

Advances in computing power over the decades have come thanks in part to our ability to make smaller and smaller transistors, a building block of electronic devices, but we are nearing the limit of the silicon materials typically used. A new technique for creating 2D oxide materials may pave the way for future high-speed electronics, according to an international team of scientists.

A new technical paper titled "Assessment of Wafer-Level Transfer Techniques of Graphene with Respect to Semiconductor Industry Requirements" was published by researchers at Infineon Technologies AG, RWTH Aachen University, Protemics,... » read more
