Synchronous Optical NetworWSynchronous Digital Hierarchy (SONET/SDH) cross connect switching structures may be made non-blocking by providing sufficient hardware resources. For example, in a three-stage Clos switching structure this is accomplished by providing a sufficient number of middle stage switches to allow connections to be made without blocking.(More)
We demonstrate a stable and strong n-type doping method to tune the electrical properties of graphene via vapor phase chemical doping with various high-molecular-weight ethylene amines. The resulting carrier concentration after doping with pentaethylenehexamine (PEHA) is as high as -1.01 × 10(13) cm(-2), which reduces the sheet resistance of graphene by up(More)
