We simulate electron transport through graphene nanoribbons of realistic size containing a p-n junction patterned by electrostatic gates. For a sharp p-n interface, Klein tunneling leads to refocusing of a divergent beam forming a Veselago lens. Wider transition regions allow only electrons with near-perpendicular incidence to pass the junction, forming a Klein collimator. Using a third nearest...
Tunnel field-effect transistors were fabricated from axially doped silicon nanowire p-n junctions grown via the vapor-liquid-solid method. Following dry thermal oxidation to form a gate dielectric shell, the nanowires have a p-n-n(+) doping profile with an abrupt n-n(+) junction, which was revealed by scanning capacitance microscopy. The lightly doped n-segment can be inverted to p(+) by modula...
In this paper, we present complete message-passing implementation that shows scalable performance while performing exact inference on arbitrary Bayesian networks. Our work is based on a parallel version of the classical technique of converting a Bayesian network to a junction tree before computing inference. We propose a parallel algorithm for constructing potential tables for a junction tree a...
In this paper, the purpose is to improve the efficiency of triple-junction solar cell by introducing quantum well into GaAs junction. Firstly, InGaP/GaAs/InGaAs triple-junctions solar cell has been simulated. Then, a multiple stepped quantum wells (MSQWs), in which InGaAs well is sandwiched by InGaAsP as stepped layer, and the barrier is GaAs, has been introduced into intrinsic region of single...
