Here is the Texas Instrument's semiconductor crystal Christmas tree from around 1959
SEMICONDUCTOR CRYSTAL CHRISTMAS TREE
In a 12-step cycle, the crystalline atoms light in sequence, illustrating the many planes in which they are oriented in a semiconductor crystal.
This demonstrator applies to Germanium, Silicon – both of which TI uses in its semiconductor products – Diamond, and compound semiconductors such as Indium Antimonide, Gallium Arsenide, Silicon Carbide and Zinc Sulfide.
The central yellow and blue round atoms form a “unit cell,” or basic crystalline building block.
The white round and blue conical atoms represent alloying elements producing semiconductor action and occurring only once in a thousand crystal segments this size.
Green and red atoms would be of different elements in the case of a compound crystal, or the same element in the case of a simple crystal.
MAGNIFICATION – 500 MILLION TIMES LIFE SIZE
