Ultrathin Epitaxial Graphite2D Electron Gas Properties

We have produced ultrathin epitaxial graphite films which show remarkable 2D electron gas (2DEG) behavior. The films, composed of typically three graphene sheets, were grown by thermal decomposition on the (0001) surface of 6HSiC, and characterized by surface science techniques. The low temperature conductance spans a range of localization regimes according to the structural state (square

Graphene Transistors Fabricated via Transfer Printing In

We demonstrate a method that uses the pillars on a stamp to cut and exfoliate graphene islands from a graphite and then uses transfer printing to place the islands from the stamp into the device active areas on a substrate with a placement accuracy potentially in nanometers. The process can be repeated to cover all device active areas over an entire wafer. We also report the transistors

Nonwoven fabric filters ScienceDirect

The pitfall of the filter efficiency of a nonwoven fabric for particles of the diameter between d p1 and d p2 is unacceptable but inevitable. To design a nonwoven filter with high filter efficiency, nonwoven fabrics composed of fibres of more than one diameter is proposed. 92 If a nonwoven filter is composed of multiple components of fibres, the filter efficiency of the nonwoven filter for
