A guided safari through the properties of over 1000 2D materials revealed by data mining techniques
Department of Materials Science and Engineering,
Two-dimensional materials and weakly bonded layered materials exhibit potentially advantageous properties as thin electronic materials, but research has been largely focused on only a couple of dozen types. We have utilized data mining approaches to elucidate over 1000 2D materials and several hundred 3D materials consisting of van der Waals bonded 1D subcomponents, or molecular wires. I will provide a guided tour of the spectrum of properties of these materials that are of interest for electronic applications. We find that hundreds of these 2D materials have the potential to exhibit observable piezoelectric effects, representing a new class of piezoelectrics. Another subset of these materials has the potential to exhibit structural changes under a variety of external stimuli including electrostatic gating. I will discuss calculations of phase diagrams, some experimental results, and potential phase change applications for these materials.
Evan Reed is a faculty member in the Department of Materials Science and Engineering at Stanford University. He received a B.S. in applied physics from Caltech (1998) and PhD. in physics from MIT (2003). In 2004, he was an E. O. Lawrence Fellow and staff scientist at Lawrence Livermore National Laboratory before moving to Stanford in 2010. His research focuses on the use and development of computational techniques to predict the properties of materials.
