讲座内容简介:
The optical and electronic properties of 2D materials and devices can be tuned in an easily and controlled fashion by different strategies. Proximity effects and nanostructuration are two important ingredients to modify the intrinsic properties of materials. New methods and concepts in the fabrication with 2D materials allow for designing novel devices in terms of properties and functionalities. Flexible, transparent and tunable devices can be fabricated almost at will by assembling building blocks of 2D materials with different properties. The tunability of the material properties can be achieved by different strategies like Straintronics, Twistronics, Iontronics, Valleytronics, one of those strategies is Strain Engineering, which provides a powerful route to modify the electrical and optical properties in 2D materials and thus it is an excellent candidate to be used as an external tuning knob. Some 2D materials can hold up to a 10-20% of strain before rupture, unprecedented in any conventional semiconductor based device. Furthermore, strain engineering techniques opens the possibility to explore new pathways in the understating of the intrinsic nature of 2D materials with different properties like 2D superconductors, magnetic and their applications.
