2D materials with atomic thickness display strong gate controllability and emerge as promising materials to build area‐efficient electronic circuits. However, achieving the effective and nondestructive modulation of carrier density/type in 2D materials is still challenging because the introduction of dopants will greatly degrade the carrier transport via Coulomb scattering. Here, a strategy to control...
We demonstrate one of the basic building elements of graphene electronics, logic inverter, based on graphene-on-boron nitride material system. The inverter is composed of two adjacent graphene-channel field-effect transistors (GFETs). The impacts of hexagonal boron nitride, a new supporting substrate material, on major device performance metrics of GFET such as small-signal transconductance g and...
Recently many countries have kept studying on the methods of constructing ultra speed networks. Task Force team for IEEE 802.3ah has accomplished the standardization of EPON which is the next generation subscriber access network. EPON doesn't still have the bandwidth wide enough to support the new service which demands high bandwidth. Therefore 10 G EPON is the next generation subscriber access network...
In this paper, we modify OLSR for MANET nodes to achieve full connection to Internet through multiple mobile gateways. We present a proactive mobile IP approach using Hello message and TC message to maintain the MANET nodes movement. The mobile gateway multiple metrics selection algorithm can select the best one among the active multiple mobile gateways. The simulation result shows that our approach...
The paper presents three-layered key management architectures to MANET (Mobile Ad hoc networks) with three-layered virtual infrastructure. Two kinds of three-layered key management architectures are introduced. The communication efficiency of them has been analyzed. It also shows that the communication cost of the three-layered key management schemes is always smaller than that of the two-layered...
