摘要

The structural parameters,electronic structure,chemical bonding and optical properties of hexagonal LiIO3 are investigated in the framework of density functional theory.The calculated lattice parameters are in agreement with the previous experimental work.The band structure,density of states,and Mulliken charge population are obtained,and indicate that hexagonal LiIO3 has an indirect band gap of 2.81 eV.Furthermore,the optical properties are also calculated and analyvzed in detail It is shown that hexagonal LiIO3 is a promising dielectric material.
