Two dimensional (2D) materials are atomically thin materials with remarkable properties such as high carrier mobility, flexibility, piezoelectricity, and tunable band structure by modification of surface states, making them attractive for flexible electronic and optoelectronic application. Recently, 2D tellurium (2D-Te) has been reported to have very high hole mobility making it a strong candidate for high frequency electronics. Potential applications of the 2D-Te devices include wireless communication in wearable medical devices and flexible electronic devices. The goal of the proposed project is to design and fabricate new high frequency electronic devices using 2D-Te. The proposed project is a collaboration between Dr. Adachi's team in the School of Engineering Science, Simon Fraser University and Dr. Renato Negra's team, Chair of High Frequency Electronics, RWTH-Aachen University, Germany. Dr. Adachi's group will synthesize and characterize the semiconductor material, 2D-Te, and design and fabricate 2D-Te devices. Dr. Negra's group will perform all high-frequency electrical characterization and circuit testing. Anticipated outcomes include the first investigation of the high-frequency operation of 2D-Te. The proposed project will also help Dr. Adachi and Dr. Negra establish a long-term international collaboration between the groups. Two PhD students in Canada will gain hands-on experience in developing high frequency device prototypes and training experience will be enhanced by regular interactions with collaborators in Germany. The development of the high frequency electronics will generate new knowledge for Canadian high-tech sector. A successful completion of this project will support the Canadian government's Recovery Plan for Jobs, Growth, and Resilience goals of "Strengthening Canada's Semiconductor Industry" and "making Canada's Economy More Competitive" by generating new knowledge on new high frequency electronic technology.
