Abstract

We use a micromechanical cantilever with an integrated two-dimensional electron system to show that an extremely small strain of the order of 10 -4 induces a localized-delocalized electronic state transition. Furthermore, by employing the large strain effects, we found that the cantilever mechanical motion is affected considerably by friction exerted by the electron system, demonstrating its utility for studying the electron energy dissipation. The strong coupling of mechanical and electronic degrees of freedom in such integrated structures provides us with a novel and powerful method with which to undertake a detailed study of electron behavior in low-dimensional semiconductor structures.
