Note: Graphene molecular nano-memory  is a novel non-volatile charge trapping memory using isolated and uniformly distributed graphene nano-crystals as nano-floating gates with controllable capacitance and excellent uniformity. The nano-graphene charge trapping memory with gate exhibits large memory voltage (4.5 V) at low operating voltage (8 V), chemical and thermal stability (1000 °C), as well as tunable memory performance using differential tunneling.

Graphene has outstanding nanoelectronic properties, very high electron mobility and unparalleled conductivity at the nanoscale. It is a superconductor, transporting electrons ten times faster than silicon. These properties    make graphene an ideal candidate for next-generation nanoelectronic applications such as graphene molecular nanomemory .




The interaction of the absorbed  nano-graphene electrons  changes the electrical conductivity of the surface of  the Nano Memory Moulcolar graphene molecular nano-memory  . The absorption of  a small amount of nano-electrons  with very low molecular motion changes the resistance of the nano-graphene  , which is proportional to the resistance of  the Nano Memory Moulcolar graphene molecular nano-memory  .  The Nano Memory Moulcolar graphene molecular  nano-memory is a transparent, flexible nano-graphene floating gate transistor memory device that is fabricated by combining a single-layer graphene active channel with gold nano-particle charge trap elements. Systematically, the sizes of the gold nano-particle charge trap elements, the thickness of the tunneling dielectric layer, and the doping level of graphene are very important in its production.  In particular, the conductivity differences (  i.e.  , the memory window) between the programming and erasing operations at a specific read gate voltage can be maximized through doping.  The resulting molecularly developed graphene nano-memory  exhibits excellent programmable nanoscale memory performance compared to previous graphene memory devices and a large memory window (12 V), fast switching speed (1 μs), strong electrical reliability. The graphene molecular nano-memory  exhibits unique electronic properties, and its small size, structural robustness, and high performance make it a very promising charge storage medium for nano-memory applications.  Along with the development of miniaturized and scaled-up devices, nanostructured graphene is emerging as an ideal material.
