    Abstract: A microelectronic device includes a gated graphene component. The gated graphene component has a graphitic layer containing one or more layers of graphene. The graphitic layer has a channel region, a first contact region adjacent to the channel region and a second contact region adjacent to the channel region. A patterned hexagonal boron nitride (hBN) layer is disposed on the graphitic layer above the channel region. A gate is located over the patterned hBN layer above the channel region. A first connection is disposed on the graphitic layer in the first contact region, and a second connection is disposed on the graphitic layer in the second contact region. The patterned hBN layer does not extend completely under the first connection or under the second connection. A method of forming the gated graphene component in the microelectronic device is disclosed.

    Abstract: A microelectronic device includes a gated graphene component over a semiconductor material. The gated graphene component includes a graphitic layer having at least one layer of graphene. The graphitic layer has a channel region, a first connection and a second connection make electrical connections to the graphitic layer adjacent to the channel region. The graphitic layer is isolated from the semiconductor material. A backgate region having a first conductivity type is disposed in the semiconductor material under the channel region. A first contact field region and a second contact field region are disposed in the semiconductor material under the first connection and the second connection, respectively. At least one of the first contact field region and the second contact field region has a second, opposite, conductivity type. A method of forming the gated graphene component in the microelectronic device with a transistor is disclosed.

    Abstract: A process of sorting metallic single wall carbon nanotubes (SWNTs) from semiconducting types by disposing the SWNTs in a dilute fluid, exposing the SWNTs to a dipole-inducing magnetic field which induces magnetic dipoles in the SWNTs so that a strength of a dipole depends on a conductivity of the SWNT containing the dipole, orienting the metallic SWNTs, and exposing the SWNTs to a magnetic field with a spatial gradient so that the oriented metallic SWNTs drift in the magnetic field gradient and thereby becomes spatially separated from the semiconducting SWNTs. An apparatus for the process of sorting SWNTs is disclosed.
