Abstract

Measurements of thermodynamic quantities provide complentary information to transport experiments. In particular, measurements of the local electronic compressibility gives unique insight into the microscopic physics of electronic interactions of two dimensional electron systems (2DES).

In this talk I will explain the measurement approach and review results on high mobility 2DES in semiconducting hetero-structures and graphene.
