If you stepped up and suggested that eliminating the substrate was the future of semiconductor manufacturing, nine times out of 10 (or 10 out of 10) you would be dismissed with a wave of the hand. That’s not too different than the initial reactions Lars Samuelson of Lund University in Sweden received when he presented that possibility to his colleagues. “When I first suggested the idea of getting rid of the substrate, people around me said ‘you’re out of your mind, Lars; that would never work,'” Samuelson relates in a release describing his latest research . But it did work and the process for doing it, which was published in the journal Nature ("Continuous gas-phase synthesis of nanowires with tunable properties "), looks like it could reach the commercial stage in applications for solar cells in as little as two to four years. The process consists of putting freely suspe...
