The road electronics did not take.
Lilienfeld anticipated field control decades before the transistor. The unanswered historical question is how far a field-first materials program could have gone without the Bell Labs route becoming the organizing story.
Lilienfeld’s patents anticipated the control topology of a field-effect device, but not a guaranteed manufacturable transistor. The materials were the problem: mobility, purity, interfaces, traps and dielectrics. Shockley’s field-effect attempts then ran into surface screening; Bardeen identified surface states; silicon dioxide passivation eventually made the surface controllable enough for MOS.
Lilienfeld anticipated an architecture. Atalla and Kahng acquired the interface that made the architecture real.
Why this belongs here
It demonstrates the difference between engineering observables and microscopic ontology. A field-effect research program could measure capacitance, conductivity, trapping, diffusion, lifetime, oxide quality and surface potential using continuum electrostatics and transport equations while deeper microscopic theory remained contested.
Likewise, drift–diffusion equations for semiconductor devices already look like classical field equations: Poisson plus continuity, drift, diffusion, generation and recombination. Standard band theory supplies the microscopic parameters and carrier interpretation; it does not follow that every successful macroscopic semiconductor calculation is itself a proof that no alternate microscopic field ontology could generate those parameters.
