We discuss the application of the hydrostatic pressure technique for the investigation of transport properties in two-dimensional systems at high magnetic fields. The experimental results cover various systems like two-dimensional electron gas systems (GaAs-AlGaAs and GalnAs-AlInAs heterojunctions) and a two-dimensional electron-hole system (a GaSb-InAs-GaSb double heterostructure). In both cases, the carrier density decreases with increasing pressure and this gives a unique opportunity to study transport phenomena as a function of either the carrier density or the degree of electron-hole compensation without having to change the sample.
