Murtaza, Ghulam Ali Hussain, Reshak, Prof.Dr. murtaza@icp.edu.pk maalidph@yahoo.co.uk Band structure DFT Hydrostatic pressure Lithium fluoride Optical properties Link to publisher's homepage at http://www.worldscientific.com/ We hereby are reporting the transition pressure at which lithium fluoride (LiF) compound transforms from direct band gap to indirect band gap insulator on the basis of FP-LAPW calculations. The fundamental band gap of LiF compound suffers direct to indirect transition at a pressure of 70 GPa. The study of the pressure effect on the optical properties e.g. dielectric function, reflectivity, refractive index and optical conductivity of LiF in the pressure between 0-100 GPa, shows that this pressure range is very critical for LiF compound as there are significant changes in the optical properties of this compound. 2014-06-19T07:51:52Z 2014-06-19T07:51:52Z 2013-04 Article Modern Physics Letters B, vol. 27(9), 2013, pages 1-9 0217-9849 (Print) 1793-6640 (Online) http://www.worldscientific.com/doi/abs/10.1142/S0217984913500619?queryID=3%2F20471 http://dspace.unimap.edu.my:80/dspace/handle/123456789/35712 10.1142/S0217984913500619 en World Scientific Publishing Co.
