1949W. Shockley in Bell Syst. Technical Jrnl. XXVIII. 435 The principles and theory of a p-n-p transistor are described. Ibid. 474 The p-n-p transistor has the interesting feature of being calculable to a high degree. 1962Simpson & Richards Physical Princ. Junction Transistors iii. 51 The diffused layer forms the base, and the original material the collector, of a high-frequency p-n-p transistor. 1967[see n-p-n]. 1975D. G. Fink Electronics Engineers' Handbk. viii. 26 The low current gain of a lateral pnp can be improved by combining it with a monolithic npn transistor, to form a composite transistor structure. |
