Located in media A discovery made at EPFL could play an important role in electronics, allowing us to make transistors that are smaller and more energy efficient. Research carried out in the Laboratory of Nanoscale Electronics and Structures (LANES) has revealed that molybdenite, or MoS2, is a very effective semiconductor. This mineral, which is abundant in nature, is often used as an element in steel alloys or as an additive in lubricants. But it had not yet been extensively studied for use in electronics Located in media < Previous 10 items 1 ... 1291 1292 1293 1294 1295 1296 1297 ... 1562 Next 10 items > Subscribe to an always-updated RSS feed.
