The electronic properties of the two-dimensional 2D electron systems in modulation-doped AlAs quantum wells are investigated, with the goal of developing this material as a sensor with an unprecedented, large sensitivity to stress andor strain. Such a sensor may find use in various scanning probe microscopes, and in other applications where minute amounts of variables such as force, displacement, or pressure need to be measured.
