Defects in Wires and Crosspoints
lNWs may break during assembly
lDiameter can be ≈100 atoms
lStatistical nature of contacts
lNW-to-MW junctions: small no. of atomic bonds
lE.g. [Huang 2001]: 95% of contacts good
lNW-to-NW junctions: composed of 10s of atoms
lE.g. [Chen 2003]: 85% of crosspoints useable
lStatistical nature of doping
lNumber of dopants per NW diameter is small
