Physics:Johnsen–Rahbek effect - HandWiki

Nettetelectroadhesive effect, as it was a highly intensified version of the AC effect. When the term Johnsen-Rahbek effect is used in literature, it solely refers to intensified electroadhesion with DC excitation. An in-depth explanation of the Johnsen-Rahbek effect is beyond the scope of this paper, but a basic explanation is as follows. NettetThe Johnsen–Rahbek effect occurs when an electric potential is applied across the boundary between a metallic surface and the surface of a semiconducting material. Under these conditions an attractive force appears, whose magnitude depends on the voltage and the specific materials involved. biol 3250 courseforum
