We report conductance and magnetoconductance measurements on narrow silicon inversion layers 40-200 nm wide, with mobilities of 1000-5000 cm2 V · s at 2 K. At high magnetic fields Shubnikov-De Haas oscillations are observed, but at zero field there still is pronounced structure in the conductance versus electron density, with irregular spacings roughly that expected from quantum confinement ("particle in a box") associated with the lithographically defined width.
