Abstract
Oscillatory magnetoresistance (Shubnikov–de Haas) measurements have been used to determine free‐carrier effective masses in HgTe‐CdTe superlattices. Measurements on an n‐type superlattice yield an electron mass that is in excellent agreement with theoretical results from a tight‐binding band‐structure calculation. The p‐type data are more complex, showing evidence for a light‐hole mass at low magnetic fields and a much heavier mass at fields above 2.0 T. This finding is also in agreement with the predictions of band‐structure theory.This publication has 9 references indexed in Scilit:
