A treasure trove for nanotechnology experts


2D materials, which consist of a few layers of atoms, may well be the future of nanotechnology. They offer potential new applications and could be used in small, higher-performance and more energy-efficient devices. 2D materials were first discovered almost 15 years ago, but only a few dozen of ...

2-D tin (stanene) without buckling

A possible topological insulator


Nagoya University-led researchers produce 2D sheets of tin atoms predicted to have exotic uses in electronics. Nagoya, Japan - Sometimes it pays to be two-dimensional. The merits of graphene, a 2D sheet of carbon atoms, are well established. In its wake have followed a host of "post-graphene ...


Extraordinarily strong nonlinear optical graphene-like material could renovate nonlinear photonics

The discovery could enable high resolution imagining at low-power


Nonlinear optics is a key enabling technology of our modern society, such as in imaging and high-speed data communication. But the traditional devices suffer from relatively small nonlinear optical coefficients of conventional optical materials. An interdisciplinary team of scientists from Aalto ...

'Rubber material' that could lead to scratch-proof paint for car


Led by Dr Elton Santos from the University's School of Mathematics and Physics, an international team of researchers have found superlubricity in a few layers of graphene - a concept where friction vanishes or very nearly vanishes. The experts also found that a few layers of hexagonal boron ...

Fluorine grants white graphene new powers


A little fluorine turns an insulating ceramic known as white graphene into a wide-bandgap semiconductor with magnetic properties. Rice University scientists said that could make the unique material suitable for electronics in extreme environments. A proof-of-concept paper from Rice researchers ...

New Method of Characterizing Graphene


Scientists have developed a new method of characterizing graphene’s properties without applying disruptive electrical contacts, allowing them to investigate both the resistance and quantum capacitance of graphene and other two-dimensional materials. Graphene consists of a single layer of carbon ...

Using light to control curvature of plastics remotely


Researchers at North Carolina State University have developed a technique that uses light to get two-dimensional (2-D) plastic sheets to curve into three-dimensional (3-D) structures, such as spheres, tubes or bowls. The advance builds on earlier work by the same research team, which focused on ...

Novel light sources made of 2D materials


Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape. So-called monolayers are at the heart of ...

Graphene key to two-dimensional semiconductor with extraordinary properties


A newly discovered method for making two-dimensional materials could lead to new and extraordinary properties, particularly in a class of materials called nitrides, say the Penn State materials scientists who discovered the process. This first-ever growth of two-dimensional gallium nitride using ...
