    摘要： A method of forming a silicon carbide transient voltage suppressor (TVS) assembly and a system for a transient voltage suppressor (TVS) assembly are provided. The TVS assembly includes a semiconductor die in a mesa structure that includes a first layer of a first wide band gap semiconductor having a conductivity of a first polarity, a second layer of the first or a second wide band gap semiconductor having a conductivity of a second polarity coupled in electrical contact with the first layer wherein the second polarity is different than the first polarity. The TVS assembly also includes a third layer of the first, the second, or a third wide band gap semiconductor having a conductivity of the first polarity coupled in electrical contact with the second layer. The layer having a conductivity of the second polarity is lightly doped relative to the layers having a conductivity of the first polarity.

    摘要： A method of manufacturing a heterostructure device is provided that includes implantation of ions into a portion of a surface of a multi-layer structure. Iodine ions are implanted between a first region and a second region to form a third region. A charge is depleted from the two dimensional electron gas (2DEG) channel in the third region to form a reversibly electrically non-conductive pathway from the first region to the second region. On applying a voltage potential to a gate electrode proximate to the third region allows electrical current to flow from the first region to the second region.

    摘要： A thermal management system includes graphene paper disposed between a heat source and a heat sink to transfer heat therebetween. The graphene paper is oriented such that the individual layers are substantially perpendicular to the plane of the heat source and the plane of the heat sink to maximize heat transfer. The heat source and the heat sink can be any physical structure that emits and absorbs thermal energy, respectively. The graphene paper may be bonded to the heat source and the heat sink using a bonding agent, such as a thermally conductive material, and the like. The graphene paper may be formed in several different configurations, such as a spring structure, and the like.
