Here we report on low temperature transport measurements of encapsulated bilayer graphene nano constrictions fabricated employing electrode-free AFM-based local anodic oxidation (LAO) nanolithography. This technique allows for the creation of constrictions

Detection of fractional quantum Hall states by entropy-sensitive measurements

Measurements of the thermopower of a clean two-dimensional electron system is directly proportional to the entropy per charge carrier1 which can probe strongly interacting quantum systems ranging from black holes2 to the fractional quantum Hall effect
