SUMMARY

This discussion focuses on the search for comprehensive literature regarding point contacts in AlGaAs/GaAs two-dimensional electron gases (2DEG), particularly their transport properties at microwave frequencies around a few GHz. Key researchers mentioned include R. R. Du from Rice University and the team of Lloyd Engel and Dan Tsui from the Magnet Lab and Princeton University, who have conducted significant microwave measurements in this area. The aim is to gather information that can aid in developing simplified lumped-element circuit models for these systems.

PREREQUISITES
  • Understanding of two-dimensional electron gas (2DEG) systems
  • Familiarity with AlGaAs/GaAs semiconductor materials
  • Knowledge of microwave frequency measurement techniques
  • Basic concepts of lumped-element circuit modeling
NEXT STEPS
  • Research recent publications by R. R. Du on point contacts in 2DEG
  • Explore the works of Lloyd Engel and Dan Tsui related to microwave measurements in GaAs/AlGaAs
  • Study the principles of quantum point contacts (QPCs) in semiconductor physics
  • Investigate circuit modeling techniques for microwave applications
USEFUL FOR

This discussion is beneficial for physicists, electrical engineers, and researchers focused on semiconductor physics, particularly those interested in the transport properties of 2DEG systems and microwave measurement techniques.

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.
 
Physics news on Phys.org
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.
