Few Hole Quantum Dots in a Gated GaAs/AlGaAs Heterostructure
(University of Waterloo, 2019-06-24)This thesis presents a set of experiments that explore gate de ned hole quantum dots in the GaAs/AlGaAs heterostructure. These experiments explore the evolution of the quantum states of holes in a double quantum dot. The ... -
Hall Resistance Characterization of Thermoelectric Materials; Subgap Leakage Measurement of Josephson Junctions
(University of Waterloo, 2020-06-01)The thesis has two parts. The first part is the Hall measurement of thermoelectric materials which are promising energy sources in the future. By characterizing the Hall resistance at different environments, their charge ... -
Investigation of Photon Interactions with Semiconductor Quantum Dot Devices for Quantum Communication Applications
(University of Waterloo, 2020-01-21)A major goal in the field of quantum communication is to achieve long-distance (>100 km) transmission of quantum information, which would allow for the formation of a global quantum network. Devices called 'quantum repeaters' ... -
Precision Low Temperature Calorimetry and Susceptibility of Magnetic Pyrochlores
(University of Waterloo, 2018-09-19)Spin-ice models feature the same statistical disorder as water ice, which is identified as the source of zero-point entropy. Gapped topological excitations with properties of monopoles are associated with the violation of ... -
RF-QPC Charge Detector and S-T₊ Qubit in a Lateral Double Quantum Dot Device
(University of Waterloo, 2017-01-18)A measurement system is developed for studying a lateral double quantum dot (DQD) device formed in the two-dimensional electron gas (2DEG) of a GaAs/AlGaAs heterostructure. Copper powder and RC filters are constructed to ... -
Setup and Design of a Cryogenic Testing Station with Focus on Characterization of Superconducting Devices
(University of Waterloo, 2019-05-23)The goal of my thesis was to construct a general purpose cryostat, capable of measuring multiple devices at 100mK. This included modifying an existing SHASTA model 106 Adiabatic Demagnetization Refrigerator (ADR) by adding ... -
Setup of Dry Cryostat for Measurements on Superconducting Microwave Resonators
(University of Waterloo, 2019-09-20)A cryogen-free cryostat was set up in order to perform measurements at ultra low temperatures. The setup involved the removal of an adiabatic demagnetization refrigerator (ADR) and replacing it with a dilution refrigerator ...
