Collection of research papers from Mullard Research Laboratories mostly relating to semiconductors. The reports in this collection were produced by the Mullard Research laboratories both at Salfords and their Southampton semiconductor facility, between 1954 and 1961. The focus of these reports is very much on the use of transistors in various applications including car radios, televisions and computers. A great deal of this focuses on research into the higher frequency and temperature difficulties that were a major drawback of earlier transistors but beyond this there are also a number of reports that detail research into laboratory use as well as studies of the materials used to produced components. 1954-1961 [MUL] Collection of Mullard Research Laboratories Reports 1954-1961
