Abstract

An analogue memory device comprises a layer of doped amorphous silicon located between a first conducting layer metal contact layer of V, Co, Ni, Pd, Fe or Mn. It has been found that the selection of one of these metals as the contact exerts a significant effect on the properties of the device, e.g. the selection of Al, Au or Cu gives no switching whereas Cr, W, Ag give digital instead of analogue switching.
