Findings may impact next-generation handheld devices, solar arrays, and basic science Unexpected voltage increases of up to 25 percent in two barely separated nanowires have been observed at Sandia National Laboratories. Designers of next-generation devices using nanowires to deliver electric currents – including telephones, handheld computers, batteries and certain solar arrays – may need to make allowances for such surprise boosts. "People have been working on nanowires...
