Small changes to the voltage of the grid control large changes in the electron current flowing to the collector plate.

ECONOMIST: The middle age of the transistor

Grandis makes a non-NAND flash solid state storage technology called spin-transfer torque RAM (STT-RAM) that stores information via the direction of magnetization in a spin-polarized electron current.

If a gas has bound to the the nanotubes it will impede the electron flow, altering the current.

BBC: MIT pencil 'draws' gas sensors onto paper

Andrew Kent, a physicist at New York University, spends most days running electricity through a magnet smaller in diameter than a single cell, trying to determine the lowest current at which an electron's spin changes orientation.
