A two-terminal device containing a single crystal of semiconducting material that ranges from P-type at one terminal to N-type at the other [7].

A bipolar transistor constructed from interacting PN junctions. The term is
used to distinguish junction transistors from other types, such as field-effect and point-contact [7].
