The Spark of Divergence: The Empirical Transistor (1920) In our timeline, the transistor was delayed until 1947 because the materials science of ultra-pure single-crystal semiconductors did not yet exist, and the quantum mechanical understanding of solids (such as Alan Wilson’s band theory) was not published until…Read the full answer

The Point of Divergence: 1920 To make this scenario plausible, we assume that Julius Lilienfeld’s theoretical patents for the field-effect transistor (FET) were accompanied by a breakthrough in materials science—specifically, the purification of germanium or silicon—allowing practical manufacturing by a major player…Read the full answer
