A new way to corrosion-proof thin atomic sheets

A variety of two-dimensional materials that have promising properties for optical, electronic, or optoelectronic applications have been held back by the fact that they quickly degrade when exposed to oxygen and water vapor. ...

Wrinkles take the heat

Single atomic sheets of black phosphorus are attracting attention for their potential in future electronics applications. A*STAR researchers have now completed experiments at the nanoscale to unlock the secret of this material's ...

Semiconductors combine forces in photocatalysis

A significant advance in the photocatalytic activity of conventional materials is demonstrated by a two-dimensional heterostructure comprising nanolayers of two semiconductors: black phosphorus and bismuth tungstate. As researchers ...

Blue phosphorus—mapped and measured for the first time

Until recently, the existence of 'blue' phosphorus was pure theory. Now, an HZB team has examined samples of blue phosphorus at BESSY II for the first time and mapped their electronic band structure. They report that it represents ...

Ultrathin black phosphorus for solar-driven hydrogen economy

Hydrogen as a fuel source, rather than hydrocarbons like oil and coal, offers many benefits. Burning hydrogen produces harmless water with the potential to eliminate carbon dioxide emissions and their environmental burden. ...

The comeback kid—black phosphorus and its new potential

When it was discovered over a century ago, black phosphorus was considered relatively useless. Over the past five years, however, the engineers and chemists have become intrigued by the material for its potential as an ultra-thin ...

Black phosphorus holds promise for the future of electronics

Discovered more than 100 years ago, black phosphorus was soon forgotten when there was no apparent use for it. In what may prove to be one of the great comeback stories of electrical engineering, it now stands to play a crucial ...
