- A connection between conductors or sections of a transmission line.
- The interface between two different semiconductor regions in a semiconductor device.
- A mechanical or alloyed contact between different metals or other materials, as in a thermocouple.
A joining or being joined.
A place or point of joining or crossing, as of highways or railroads.
