A new approach to developing semiconductor materials at tiny scales could help boost applications that rely on converting light to energy. A Los Alamos-led research team incorporated magnetic dopants ...

Quantum computers can solve numerous problems faster, based on quantum properties such as superposition and entanglement, than classical computers. For example, Shor’s algorithm 1, proposed by Peter ...

Large numbers can only be factorized with a great deal of computational effort. Physicists at the University of Innsbruck, Austria, led by Wolfgang Lechner are now providing a blueprint for a new type ...

Researchers have made a breakthrough in quantum dot technology, significantly raising this technology's ability to convert light into energy or chemical products. “Our work demonstrates how purely ...

To generate a current, a negative voltage is initially applied to two gate electrodes, creating quantum dots in a silicon wire (Figure 2). Then, by applying a positive voltage to one of the gate ...

Multiple exciton generation (MEG) in quantum dot (QD) photovoltaics offers a route to surpass the Shockley–Queisser limit by converting the excess energy of a single high-energy photon into more than ...
