The innovation has been announced by Professor Justin Holmes, a scientific investigator at the Advanced Materials and BioEngineering Research Centre and professor of nanochemistry at University College Cork.
The tin-germanium mixture has been used by Holmes and his team to make tiny electricity-conducting wires, called nanowires. These control the electrical flow in devices, as silicon does, but use less power.
Low-power electronics could mean that mobile phones need to be charged less often, Holmes said, and could open the way for solar-powered mobile phones.
“Improved power efficiency means increased battery life for mobile devices, which ultimately leads to lower greenhouse gas emissions,” he said. “The charging of mobile electronic devices currently accounts for 15% of all household electricity consumption.”
The technical problem with having billions of transistors in a single silicon switch is that the amount of heat generated has shortened battery life and can lead to overheating.
This prompted scientists including Holmes to look at different materials that could be used in chips. IQE said it hopes the Irish-made material will make silicon chips faster and reduce their power consumption.
“The ability to increase the speed and number of devices on a chip by reducing size is coming to an end. Novel ideas such as nanowires will allow the microelectronics revolution to continue,” it said.
The justification for torture in Northern Ireland, Iraq, Algeria and many other places has always been that, while distasteful, it produces results that save innocent lives.
This premise is scientifically bogus, according to TCD neuroscientist Professor Shane O’Mara. The neuroscientist details exactly why in his new book ‘Why Torture Doesn’t Work‘ (Harvard University Press)
