TI number: G00436
Transistor Demonstration, Germanium - This item is part of the amplifer for a 45 rpm record player which was used in demonstrations of the tolerance silicon transistor have for high temperatures. The circuit on this paddle contains germanium grown junction transistors.

A companion paddle using some of the original experimental silicon transistors was also used in the demonstration. The record player was operated using the germanium paddle which was then dipped into a beaker of hot oil. As the transistors heated up, the sound died out. The silicon amplifier paddle was then connected and the procedure repeated. In this case, as the transistors heated up the sound continued with no change. This equipment was first used by Gordon Teal in his May 10, 1954, talk in which he announced that TI had silicon transistors in production. The demonstration was repeated numerous times for customer visits and trade exhibits. The silicon paddle and the 45 rpm record player have been lost in the interim moves and shuffles. For additional information, see the copy of Teal's talk at the 25th Anniversary Observance Transistor Radio and Silicon Transistor. The booklet is in the Artifact Historical Files under Z00107-8, G00124 and G00436.

TI number: G00299
Crystal, Germanium - This is an experimental crystal grown in about 1957. The object was to grow the largest possible diameter single crystal from a molten quantity then limited in amount by the available equipment capacity.

The object of this experimental work done by Dr. Walt Runyan was a slice of single crystal semiconductor material for use as a lens for infrared sensing equipment. The size of the available crystal pullers and heating equipment limited the volume of charge that could be handled. See related material for additional experimental results.

TI number: G00322
Crystal, Germanium - The item is a piece of a gallium doped germanium single crystal which was part of an experiment involving a space grown crystal to study the influence of gravity on crystal growth.

The experiment was done in conjunction with NASA Marshall Space Flight Center in 1973. Three identical sets of germanium crystals were prepared in SRDL and sent to MSFC. One set was melted and regrown in a zero gravity environment aboard Skylab Mission No. 2, May 25- June 22, 1973. The other two sets received the same crystal growth experiment in a normal gravity environment at MSFC. This item is from crystal 5C which was part of the latter experiment. Measurements indicated major reductions in segregation for the space grown crystals. For details of the experiments and results, see the TI Technical Report by J.T. Yue and F.W. Voltmer entitles "The Influence of Gravity-Free Solidification on Micro segregation". A copy is in the Artifacts Historical Files.

Transistor, Germanium Epitaxial Planar - This transistor type is a PNP germanium epitaxial planar device designed for microwave applications. It was one of the first, if not the first, transistor of this type built for microwave use.

This transistor was developed at TI in early 1965. The experimental type number TIXM101 was assigned in January, 1965. The production devices were designated TIM101 until the specifications were registered with JEDEC, which assigned it type number 2N5043. These two devices have the 611A date code which shows them to be from the first lot of the eleventh week of 1966.
