Earlier this year, Kis&#8217;s team demonstrated the capabilities and advantages of molybdenite as a <a href=\"http:\/\/www.nature.com\/nnano\/journal\/v6\/n3\/full\/nnano.2010.279.html\">replacement for silicon<\/a> on semiconductors.<\/p>\n<p>Molybdenite has been used in <a href=\"http:\/\/www.engineersedge.com\/lubrication\/molybdenum_disulfide_characteristics.htm\">industry as a lubricant<\/a>, particularly for munitions, but the EPFL researchers were the first to show its electrical properties. The material has a two-dimensional structure, making it less voluminous than three-dimensional silicon and thus better suited for miniaturized applications.<\/p>\n<p>Graphene is also a two-dimensional material, but unlike graphene, molybdenite has a &#8220;band-gap&#8221; &#8212; a space free of electrons that makes possible greater control over electrical properties &#8212; and thus a better platform for transistors. Kis says that as a result of these capabilities, molybdenite &#8220;can be worked in layers only three atoms thick, making it possible to build chips that are at least three times smaller.&#8221;<\/p>\n<p>Molybdenite shares silicon&#8217;s ability to amplify signals, another property graphene lacks, generating an output signal four times stronger than the incoming signal. This capability, says Kis, gives it &#8220;considerable potential for creating more complex chips.&#8221;<\/p>\n<p>Read more: <a href=\"http:\/\/sciencebusiness.technewslit.com\/?p=6131\" rel=\"prev\">Semiconductor Foundation, NSF Fund Nanoelectronics Research<\/a><\/p>\n<p style=\"text-align: center;\">*\u00a0\u00a0\u00a0\u00a0 *\u00a0\u00a0\u00a0\u00a0 *<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers at Ecole Polytechnique F\u00e9d\u00e9rale de Lausanne in Switzerland have developed the first microchip on a molybdenite platform.
