Abstract
We have measured the Hall voltage developed across a narrow, high-mobility two-dimensional electron gas of variable width. For narrow channels, the Hall voltage vanishes when the prependicular magnetic field is reduced below a certain, critical value. If the magnetic field is kept constant as the width of the channel is reduced, the Hall voltage shows large departures from the classically expected result.Keywords
