High frequency electronics based on two-dimensional tellurium

二维（2D）材料是原子级薄的材料，具有显著的性质，例如高载流子迁移率、柔性、压电性和通过表面状态的修改可调谐的能带结构，使它们对于柔性电子和光电应用具有吸引力。最近，2D碲（2D-Te）已被报道具有非常高的空穴迁移率，使其成为高频电子学的强有力的候选者。2D-Te器件的潜在应用包括可穿戴医疗设备和柔性电子设备中的无线通信。该项目的目标是利用2D-Te设计和制造新的高频电子器件。拟议的项目是西蒙弗雷泽大学工程科学学院阿达奇博士的团队和德国亚琛RWTH大学高频电子学主席Renato Negra博士的团队之间的合作。 阿达奇博士的小组将合成和表征半导体材料2D-Te，并设计和制造2D-Te器件。 Negra博士的团队将执行所有高频电气特性和电路测试。预期的成果包括2D-Te高频操作的首次调查。拟议的项目还将帮助阿达奇博士和内格拉博士在两个小组之间建立长期的国际合作。加拿大的两名博士生将获得开发高频设备原型的实践经验，培训经验将通过与德国合作者的定期互动得到加强。高频电子学的发展将为加拿大高科技部门带来新的知识。该项目的成功完成将支持加拿大政府的就业，增长和恢复计划的目标“加强加拿大的半导体产业”和“通过产生新的高频电子技术的新知识，使加拿大的经济更具竞争力”。

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.
