Weak Localization Thickness Measurements of Si:P Delta-Layers

, 2004
We report on our results for the characterization of Si:P delta-layers grown by low temperature molecular beam epitaxy. Our data shows that the effective thickness of a delta-layer can be obtained through a weak localization analysis of electrical ...
