Stretching to perfection of 2-D semiconductors

Wed, 15 Nov 2017 07:59:24 EST

Compressing a semiconductor to bring atoms closer together or stretching it to move them farther apart can dramatically change how electricity flows and how light is emitted. Scientists found an innovative way to compress or stretch very thin (monolayer and bilayer) films of tungsten diselenide by placing the film on different surfaces at high temperatures. The underlying surface stretched or compressed upon cooling. Why? With few exceptions, all materials expand when heated and contract when cooled. However, this change happens at different rates. Because the films respond at a different rate than the surface, the films stretch or compress upon cooling. Excitingly, the electronic properties of the stretched films were dramatically different.

Butterfly wing inspires photovoltaics: Light absorption can be enhanced by up to 200 percent

Tue, 14 Nov 2017 11:50:46 EST

Researchers of Karlsruhe Institute of Technology (KIT) have now succeeded in transferring these nanostructures to solar cells and, thus, enhancing their light absorption rate by up to 200 percent. The scientists report their results in the journal Science Advances.

Factors in the fabrication of heterojunctions of 2-D materials through CVD

Mon, 13 Nov 2017 05:41:04 EST

2-D materials have special lattice structures. Atoms in the same layer are usually bound by a covalent bond, while the force between layers is van der Waals coupling. They have super-clean surfaces without any dangling bonds. Thus, the design of heterojunctions is more flexible when 2-D materials are utilized to constitute heterojunctions. The heterojunctions formed by different 2-D materials have advantageous properties, including optimizing band alignment, bandgap, charge transfer and optical properties.

Condensation-based method could create stable nanoscale emulsions

Wed, 08 Nov 2017 09:08:10 EST

Now, a new finding from researchers at MIT might turn that expression on its head, providing a way to get the two substances to mix and remain stable for long periods—no shaking required. The process may find applications in pharmaceuticals, cosmetics, and processed foods, among other areas.
