Abstract

A quantity of fundamental interest for the study of semiconductors is the ground-state charge-density distribution. This is surprisingly difficult to measure with sufficient accuracy to reveal bonding effects in crystals, since the bond charge typically represents less than 0.01% of the total charge-density. For semiconductors containing a center of symmetry for which large single crystals can be grown (such as silicon), X-ray diffraction techniques can produce rather accurate results1. An urgent need exists, however, for a method which can be applied to non-centrosymmetric semiconductors and other materials which are crystalline only on a sub-micron scale.
