Abstract
The Dingle plot of Shubnikov-de Haas oscillations in quasi-one-dimensional GaAs-AlGaAs heterojunctions fabricated by wet etching is found to exhibit a deviation from linearity. It is possible to extract an effective conducting width of the wire from such a plot which is found to be in good agreement with the width derived from one-dimensional subband depopulation effects.Keywords
