Commercially viable technology revealed for large, flexible arrays of microscale solar cells and LEDs based on processing semiconductor powders or fines. Versatilis shows how key semiconductor particles, widely available at low cost, often a waste by-product of other semiconductor processes or readily synthesized, can be rapidly deposited as a closely packed monolayer and then further processed into functional micro-devices.
Electrical engineers have demonstrated a new kind of building block for digital integrated circuits. Their experiments show that future computer chips could be based on three-dimensional arrangements of nanometer-scale magnets instead of transistors. As CMOS, the main enabling technology of the semiconductor industry, approaches fundamental limits, researchers are exploring 'magnetic computing' as an alternative.
