Band-edge properties of a semiconductor alloy: An NMR study of Hg1-xCdxTe. Academic Article

abstract

• We report Hg199 NMR measurements of narrow-gap Hg1-xCdxTe alloys in the range x=0.200.28. By studying temperature dependences, we have identified intrinsic Knight shifts in these alloys. This provides a measure of Hg orbital contributions to conduction-electron states, and we find a consistently strong average contribution from Hg s orbitals. Furthermore, we identify local variations in the Knight shift with spatial variations in conduction-electron densities and symmetries. These characteristics have been related to randomly populated sites within the alloys. We also discuss Hg199 chemical shifts and their relation to local orbital charges. 1993 The American Physical Society.
