Abstract
We have measured the low temperature and low field MR of a high mobility Ge 2DHG. The resulting MR curves demonstrate WL-like behavior at temperatures below 2K with WAL-like behavior appearing between 3K and 12K. Evidence of WAL has not been previously observed in Ge. We believe this transition to be the result of a summation of WL and WAL effects in the main conduction channel and parallel conduction channel(s).This is a promising result for Ge as a possible channel for future spin-FETs.
