Researchers from the University of New South Wales have found a way of improving the emission efficiency of bulk silicon by a factor of 100, by using established solar cell technology.

Getting light out of silicon has so far only resulted in devices with power conversion efficiencies of around 0.01%. The team has achieved an efficiency of about 1%.

reverse breakdown voltage

Solar cells are designed to absorb as much light as possible and turn it into electricity; the reverse happens in LEDs. But anything that absorbs light can also emit it, meaning that solar cell designs can also be used to make LEDs.

Silicon-based semiconductors are poor light emitters due to the large refractive index difference between silicon and air. Only light that is nearly perpendicular to the interface can escape.

By break the surface up into many different angles, the re-searchers increased the amount of emitted light. The process involves etching inverted pyramids into the surface using an 'anisotropic' technique that etches certain crystal planes and not others. This improved efficiency by a factor of 10.

A further 10-fold improvement was made by reducing imperfections in the crystal as these defects allow energy to be released as heat not light.

Macaulay says that this is why IoT security needs to move from being a static process to a dynamic process. In other words, rather than accepting a set of security controls defined by a vendor, one needs to be designing for a dynamic approach to threat hunting. This also results in the need for cryptographic agility — being able to move from one cryptographic algorithm or function to another without having to re-flash or tear the device apart.

The U.K. drone attacks have closed Gatwick Airport for most of the day and caused huge disruption, not just for U.K. passengers but other international airports with scheduled flights to and from Gatwick. There has been much debate today about regulation and no-fly zones for drones around airports. Plus, the debate around technology has also ensued, asking why technology cannot prevent (through GPS geo-fencing, for example) or pinpoint the source of such attacks or where they are being controlled from. We know that they are industrial-grade drones and not hobby drones, so it’s likely to be a deliberate attempt to bring chaos.

While the range of the drones might be about 30 minutes with typical battery capacity, if the drones use cellular connectivity, they may just be operated from anywhere in the world. If anyone has seen the movie Eye in the Sky,” they’ll recognize the potential for someone to be sitting anywhere in the world and manipulate a drone to do just about anything anywhere (in the movie, the operators are acting as a team from desks in Nevada, Hawaii, London, and Kenya).

It’s timely that the GAO report from the U.S. should highlight threats such as these — which are not just long-term possibilities but, as we’ve seen, have the potential for disruption or harm here and now today. And with quantum computing just around the corner, we need to start thinking about new dynamic approaches to security.

BERLIN — Merging broadcast TV with the Web, Matsushita, Philips and Sony separately rolled out the first digital televisions and set-top boxes based on the Multimedia Home Platform here this week at Europe's largest consumer electronics show, the Internationale Funkausstellung. The systems arrive as Europe readies Internet and digital TV services that leverage the Java-based application programming interface.
