Getting something from nothing sounds like a good deal, so for years scientists have been trying to exploit the tiny amount of energy that arises when objects are brought very close together. It's a source of energy so obscure ...
A team of researchers led by Caltech's Hyuck Choo has developed an eye implant for glaucoma patients that could one day lead to more timely and effective treatment.
A new material has been shown to have the capability to double the efficiency of solar cells by researchers at Purdue University and the National Renewable Energy Laboratory.
Light behaves in rather tame and predictable ways when interacting with everyday objects—it travels in straight lines, rebounds when it hits shiny surfaces, and gets bent by lenses. But weird and wonderful things start to ...
It would be difficult to overestimate the importance of silicon when it comes to computing, solar energy, and other technological applications. (Not to mention the fact that it makes up an awful lot of the Earth's crust.) ...
Researchers at The Australian National University (ANU) have achieved a new record efficiency for low-cost semi-transparent perovskite solar cells in a breakthrough that could bring down the cost of generating solar electricity.
From an electron's point of view, graphene must be a hair-raising thrill ride. For years, scientists have observed that electrons can blitz through graphene at velocities approaching the speed of light, far faster than they ...
Contrary to the tremendous success story of electronic integration, photonic integration is still in its infancy. One the most serious obstacles it faces is the need to use a variety of materials to achieve different functions—unlike ...
Tiny "black holes" on a silicon wafer make for a new type of photodetector that could move more data at lower cost around the world or across a datacenter. The technology, developed by electrical engineers at the University ...
In a special, dust-free, clean laboratory, straddling the Swiss-French border, a group of physicists spend their time probing hand-sized hexagons of silicon. These hexagons are a fraction of a millimetre thick and are made ...
