<p>The present disclosure provides an apparatus and method for implementing a high hole mobility p-channel Germanium ("Ge") transistor structure on a Silicon ("Si") substrate. One exemplary apparatus may include a buffer layer including a GaAs nucleation layer, a first GaAs buffer layer, and a second GaAs buffer layer. The exemplary apparatus may further include a bottom barrier on the second GaAs buffer layer and having a band gap greater than 1.1 eV, a Ge active channel layer on the bottom barrier and having a valence band offset relative to the bottom barrier that is greater than 0.3 eV, and an AlAs top barrier on the Ge active channel layer wherein the AlAs top barrier has a band gap greater than 1.1 eV. Of course, many alternatives, variations and modifications are possible without departing from this embodiment.</p> |
