Fundamental Insights and Perspectives into Novel 2D Anisotropic Materials*

Anisotropic 2D materials (pseudo-1D crystals) are a new class of materials in which atoms are
confined in 2D but are arranged in a way that they form 1D chain-like features running across
one specific lattice direction. They exhibit direction and polarization dependent properties that
allow for a new degree of freedom, which are particularly attractive for a number of advanced
photonic, optics, and optoelectronic applications. In a sense, they offer unique properties that
fall between traditional 1D and 2D material systems. This talk summarizes recent advances made
in pseudo-1D material synthesis, characterization, fundamental understanding, and applications
by the team led by Prof. Tongay at Arizona State University. Special emphasis will be given to
recent projects by Tongay's team using novel grwoth methods, one-of-a-kind spectroscopy, microscopy, scanning
transmission electron microscopy (STEM), high-resolution TEM (HRTEM), and spectroscopy
facilities at Arizona State University.
