1782 tr. A. Volta in Philos. Trans. (Royal Soc.) 72 p. xii The surface of those bodies does not contract any electricity, or if any electricity adheres to them, it vanishes soon, on account of their semi-conducting nature.

1787 T. Cavallo in Philos. Trans. (Royal Soc.) 78 7 A semi-conducting or imperfectly insulating plane.

1884 J. T. Sprague Electr. (ed. 2) xiii. 573 A semi-conducting incandescent material compounded of infusible earths and carbon or metals.

1975 D. G. Fink Electronics Engineers' Handbk. vii. 31 By far the most widely used semiconducting materials are germanium and silicon.

1953 Proc. Inst. Electr. Engineers 100 i. 76/2 The value of semi~conductive glaze lies in its use in situations where trouble is expected due to flashover of insulators under adverse weather..conditions.

1960 Cambr. Rev. 27 Feb. 394/1 Although a Cambridge physicist, A. H. Wilson, put forward the basic theory of their behaviour in 1931, it is really only in the last ten years that the phenomena of semiconductivity have been clearly understood.
