<p>A switch comprises at least a first layer (1) of a first material and two contact electrodes (2, 3) arranged on said first layer on opposite sides thereof and connectable to different potentials for applying a voltage thereacross. A first layer is adapted to be conducting upon applying a voltage across said contact electrodes when exposed to irradiation through an irradiation source (4, 5) of an energy high enough for lifting charge carriers from the valence band to the conduction band of said first material. The contact electrode (2) arranged on the first side (6) of the first layer is laterally displaced with respect to the contact electrode (3) arranged on the opposite second side (7) of the layer with a lateral distance separating them.</p> |
