Abstract: Pauli-spin blockade (PSB) is a common method of spin-to-charge conversion used for readout of spin based qubits in double quantum dot architectures. A prerequisite to studies of PSB is a strong understanding of bias triangles in the absence of blockade. To this end I will present measurements of bias triangles in various biasing configurations. I use these measurements to validate a new analysis technique allowing the data to be presented in chemical potential space as opposed to the usual gate voltage space. This analysis allows comparisons between different biasing directions to be made in a clean and straightforward manner. This ability will be useful for investigations into PSB where these comparisons are paramount.
