Abstract/Description: This thesis presents work on optimizing a local annealing process for creating Ohmic contacts to a 2D electron gas (2DEG) within a GaAs/AlGaAs heterostructure. The optimization of this process will allow for fabrication of Hall devices to be used in the study of magnetic properties in quantum dots. To confirm good Ohmic contacts had been made to the 2DEG, data including IV characteristics was collected to show a linear relationship between current and voltage. Also, in order to preserve the sample and its magnetic properties, temperature was measured near the contact to confirm that the contacts were heated to about 415°C with the quantum dots at a temperature between 200°C and 250°C.
