[Also in Division C7] A semi-conductor material consists of more than doping amounts of each of three or more of the elements Se, Te, Tl and As in the ranges: apart from incidental impurities and/or impurities. In a modification the material consists of: The material is made by melting the components together and rapidly cooling the melt, by sintering a compacted powder mixture in an oxygen free atmosphere by codeposition of the individual materials on a substrate by vacuum deposition. A semi-conductor component made from this material has at least two electrodes and has a resistance which falls suddenly as the voltage between the electrodes is increased and rises again to its original value as the current is decreased. |
