  • Patent number: 8866005
    Abstract: A new solar cell structure called a heterojunction barrier solar cell is described. As with previously reported quantum-well and quantum-dot solar cell structures, a layer of narrow band-gap material, such as GaAs or indium-rich InGaP, is inserted into the depletion region of a wide band-gap PN junction. Rather than being thin, however, the layer of narrow band-gap material is about 400-430 nm wide and forms a single, ultrawide well in the depletion region. Thin (e.g., 20-50 nm), wide band-gap InGaP barrier layers in the depletion region reduce the diode dark current. Engineering the electric field and barrier profile of the absorber layer, barrier layer, and p-type layer of the PN junction maximizes photogenerated carrier escape. This new twist on nanostructured solar cell design allows the separate optimization of current and voltage to maximize conversion efficiency.

  • Publication number: 20140155253
    Abstract: Two methods of producing nano-pads of catalytic metal for growth of single walled carbon nanotubes (SWCNT) are disclosed. Both methods utilize a shadow mask technique, wherein the nano-pads are deposited from the catalytic metal source positioned under the angle toward the vertical walls of the opening, so that these walls serve as a shadow mask. In the first case, the vertical walls of the photo-resist around the opening are used as a shadow mask, while in the second case the opening is made in a thin layer of the dielectric layer serving as a shadow mask. Both methods produce the nano-pad areas sufficiently small for the growth of the SWCNT from the catalytic metal balls created after high temperature melting of the nano-pads.

  • Patent number: 8703558
    Abstract: The invention provides a graphene device structure and a method for manufacturing the same, the device structure comprising a graphene layer; a gate region in contact with the graphene layer; semiconductor doped regions formed in the two opposite sides of the gate region and in contact with the graphene layer, wherein the semiconductor doped regions are isolated from the gate region; a contact formed on the gate region and contacts formed on the semiconductor doped regions. The on-off ratio of the graphene device is increased through the semiconductor doped regions without increasing the band gap of the graphene material, i.e., without affecting the mobility of the material or the speed of the device, thereby increasing the applicability of the graphene material in CMOS devices.

  • Patent number: 8696938
    Abstract: The present invention provides a process for producing pristine or non-oxidized nano graphene platelets (NGPs) that are highly conductive. The process comprises: (i) subjecting a graphitic material to a supercritical fluid at a first temperature and a first pressure for a first period of time in a pressure vessel and then (ii) rapidly depressurizing the fluid at a fluid release rate sufficient for effecting exfoliation of the graphitic material to obtain the NGP material. Conductive NGPs can be used as a conductive additive in transparent electrodes for solar cells or flat panel displays (e.g., to replace expensive indium-tin oxide), battery and supercapacitor electrodes, and nanocomposite for electromagnetic wave interference (EMI) shielding and static charge dissipation, etc.
