Johnsen-Rahbek-Effekt – Wikipedia

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. NettetThe IBM reference specifically states that the Edison patent does not involve this effect, only resembles it, so I removed the claim that it was the first use. Although a device … eta-u90ewe
