Modeling the patterned two-dimensional electron gas: Electrostatics
... gas (2DEG) in a III–V heterostructure where scattering is small because of the separation between the donors and electrons. The electrons are then guided by electrostatic fields produced by patterned gates on the surface of the structure to produce long wires3,4 (equivalent to electromagnetic wavegu ...

... problems are contained in NPC. Therefore, problems in the intersection of NP and co-NP , if not in P , are good candidates for inclusion in NPI. In fact, a problem in NP ∩ co−NP that is believed not in P is the FACTORING problem. As already noted, FACTORING is in NP because, if we are offered a fact ...
