photoconductionn.

Brit.

/ˌfəʊtəʊkənˈdʌkʃn/, U.S.

/ˈˌfoʊdəkənˈdəkʃ(ə)n/

Origin: Formed within English, by compounding. Etymons: photo- comb. form, conduction n.

Etymology: < photo- comb. form + conduction n. With sense 2 compare photoconductive adj., photoconductor n., and also slightly earlier photoconducting adj. and photoconductivity n.

1. Botany. The conduction of a phototropic stimulus from its point of perception in a plant to the point of response. rare. Now disused.

1914 Bot. Gaz. 58 90 Dewers finds that geo-conduction and photoconduction and reaction run parallel in these organs.

2. Physics. = photoconductivity n.
