Invention of the Point-Contact Transistor

Invention of the Point-Contact Transistor

John Bardeen and Walter Brattain successfully demonstrate the first working point-contact transistor, amplifying electrical signals without vacuum tubes, under the watchful eye of William Shockley.

Setting

Bell Labs research laboratory, Murray Hill, New Jersey. A mid-sized room with workbenches covered in electronic components and testing equipment. The walls are lined with chalkboards filled with equations and diagrams. Large windows reveal a winter landscape outside.

SELECTED
John Bardeen
primary
A slender man in his late 30s with thinning dark hair combed neatly back, wearing round wire-framed glasses that magnify his intense gaze. His face carries the faint lines of prolonged concentration, with a clean-shaven jawline and slightly pursed lips that suggest habitual deep thought.
Walter Brattain
primary
A lean, wiry man in his mid-40s with sharp features, deep-set eyes, and thin lips often pressed in concentration. His dark hair is receding at the temples, and his hands bear faint burn marks from years of lab work.
William Shockley
secondary
A lean, sharp-featured man in his late 30s with slicked-back dark hair and a penetrating gaze. His angular face is clean-shaven, and he wears round wire-rimmed glasses that reflect the laboratory lights. His posture is rigid, suggesting military discipline.
Lab Assistant
background
A young man in his early 20s with a slender build, short brown hair neatly combed to the side, and wire-rimmed glasses that reflect the laboratory lights. His hands are slightly stained with machine oil from handling equipment.

Dialog

Walter Brattain Look here—current's amplifying at the contact point, John! Oscilloscope shows gain of fifteen decibels clear as day.
John Bardeen If we consider the surface state hypothesis... yes, that'd explain the carrier injection pattern. Walter, try shifting the electrode angle—
William Shockley Aren't you overlooking the minority carrier diffusion theory? My memos from March clearly established—
Walter Brattain Theory be damned, Bill—the electrons are voting with their feet! See that spike? Solid-state amplification right in our hands.
John Bardeen (clears throat) Surface recombination explains the nonlinear response. We should document the gold-bonded contacts before—
William Shockley The patent submission will require proper theoretical framework. I trust you'll both review my field-effect transistor notes from '39?
Walter Brattain Later, Bill—John, look at that trace! We've got negative resistance building at the second contact. That's no fluke.
