I want to know the answer to the following question:
What were gold contacts attached to to increase signal output?
All the background I'm provided with is that "Having unearthed Lilienfeld’s patents that went into obscurity years earlier, lawyers at Bell Labs advised against Shockley's proposal because the idea of a field-effect transistor that used an electric field as a "grid" was not new.". Is that enough to answer the question?
Answer: no
