Good review of point contacts in 2DEG?

[f95toli]

As the title says, does anyone know of a good book or review article about point contacts (both quantum and "classical" non-quantized version) in AlGaAs/GaAs 2DEG?
I am trying to find some information about their transport properties at MW frequencies (a few GHz), specifically information that can be used to create simplified lumped-element circuit models.

I can't name any reviews, but a few groups come to mind - R. R. Du (Rice U) and Lloyd Engel + Dan Tsui (Magnet Lab + Princeton). You might want to see if they have any recent reviews or papers on the field. I'm not sure if either team has worked specifically with QPCs, but I know they both have done a number of microwave measurements on GaAs/AlGaAs 2DEGs.
