Abstract Scope |
Two-dimensional (2D) materials hold a great potential as critical components of future generations of energy-efficient electronic devices such as quantum computers. Hexagons are the dominant building blocks adopted by nearly all of the promising 2D materials such as single-layer molybdenum disulphide and chromium triiodide exhibiting exotic electrical and magnetic properties, respectively. We have recently spent efforts in discovering and designing 2D materials based on pentagonal geometries possessing intrinsic anisotropy. From the tessellation point of view, there are 15 types of convex pentagons discovered so far capable of tiling a gapless plane. Namely, any of these 15 types of pentagonal can be adopted as the crystal structure of a 2D material. In this talk, We will show several examples of 2D materials with pentagonal structure, which are predicted to possess a variety of attractive properties from being an antiferromagnetic and semiconducting to the rare coexistence of ferromagnetic ordering and piezoelectricity. |
