Why don't the electron from the surface donor states recombine with the +ve polarization sheet charge in the AlGaN-side in the interface in AlGaN/GaN?

We know that most of the 2DEG-electrons in the undoped AlGaN/GaN heterostructure comes from the surface donor states (UK Mishra et. al and Guang et. al.). These electrons are driven by the...
