Detailed Technology Description

None

*Abstract

In current devices, SWNT sheets are used as actuation elements, wherein high switch voltage is required. Further, more fabrication and processing steps are carried out for device designing, which leads to higher production cost. Such devices have less storage density due to absence of nanoscale dimensions. Other prior art systems use SWNTs in forms of assembled nanowires as memory devices, which are difficult to produce and commercialize due to associated chemical assembly problems. This novel bistable nanoswitch overcomes most of these prior art limitations, providing a high density and a low power non-volatile storage system.
