Abstract
784,782. Plate rectifiers. SIEMENSSCHUCKERTWERKE AKT.-GES. Feb. 10, 1954 [Feb. 10, 1953], No. 3963/54. Drawings to Specification. Class 37. A selenium rectifier is produced by building up the selenium in plurality of layers, each layer including as a first additive a halogen, or halogen compound which increases the conductivity of the selenium and the layer adjacent the barrier layer (and if more than two layers are involved, the next adjacent layers excepting one or more of the last layers) also including a second additive such as thallium, which promotes the formation of the barrier layer, the quantity of the second additive in each layer progressively increasing in the direction approaching the barrier layer. The first addition may consist of C1, I, Br, Se 2 Cl 2 , Sa 2 Br 2' SeCl 4 or SeBr 4 and the second additive of Sb, Bi, Sn, Tl, In, Ga, Cd, Cu, Pb, As or S, or alloys or compounds thereof. The presence of the second additive will reduce the conductivity of the layer, but this may be compensated for by increasing the quantity of halogen. The second layer may be applied before or after the first layer has been rendered crystalline. Before applying the counter electrode, which may consist of Bi, Sn, Cd or alloys thereof. an additional layer of CdSe, CdS or SeO 2 may be applied.
