Internship – Electrical Characterization of Memristors
Poject title : Electrical characterization of memristors in cryogenic environment for non-volatile silicon qubits realization
Description: As part of a research program whose goal is to co-integrate memristors (resistive memories) and quantum dots on silicon for the realization of non-volatile qubits, it is first necessary to demonstrate the proper operation of memristors at cryogenic temperature (~20 mK). The proposed internship focuses on an in-depth study of the behavior and performance of TiO2-based memristors in a cryogenic environment using advanced electrical characterizations. The latter will first be performed at room temperature at the Institut Interdisciplinaire d’Innovation Technologique (3IT) to ensure that the memories are functional. Subsequently, the electrical measurements in cryogenic environment will be carried out at the Institut Quantique (IQ) and will be focused on the study of the overall performance of memristors: set/reset voltages, endurance, analog behavior of the resistance. Comparative statistical studies will also be carried out to determine the influence of temperature on operating voltages, variability, maximum number of cycles, noise or resistance programming accuracy. This work will require (i) a deep understanding of the manufacturing process and operating principle of the studied memristors; (ii) the development of electrical characterization protocols at ambient temperature and in a cryogenic environment; (iii) the analysis of the data collected and their physical interpretation; (iv) interactions with students in charge of making and simulating memristors at 3IT to improve processes and models.
Work environment: This internship will be conducted under the co-supervision of Pr. Dominique Drouin (3IT) and Pr. Michel Pioro-Ladrière (IQ). 3IT is a unique institute in Canada, specializing in the research and development of innovative technologies for energy, electronics, robotics and health. The IQ is a state-of-the-art institute whose mission is to invent the quantum technologies of tomorrow and transfer them to an industrial environment. The student will thus benefit from an exceptional research environment that combines students, professionals, professors and industrialists working hand-in-hand to develop the technologies of the future.
Specific requirements: The candidate must have a good academic record (average above 3.0), aptitude for manual laboratory work, data analysis, strong adaptability and a taste for research and development (R&D).
