Penentuan Stopping Power dan Inelastic Mean Free Path Elektron dari Aluminium Oksida pada Energi 300 eV - 50 keV

摘要

AbstractudThis research is focused on calculation of SP (Stopping Power) and IMFP (Inelastic Mean Free Path) of lanthanum aluminate for electron energy from 300 eV to 50 keV by using the equation Born Occurd correction. The calculation method has been performed by using Composite Simpson Integral. The composition of lanthanum aluminate (La2O3) x (Al2O3) 1-x was varied with x = 0.25, 0.34, and 0.5. Energy Loss Function (ELF) obtained through the Drude - Lindhard equation with input parameters: Band Gap, oscillator strength (Ai), damping coefficient (??i), and excitation energy (??i). The ELF function was used to determine the SP and IMFP. The result shows that SP value decrease. ududKeywords: Lanthanum aluminate, ELF, SP, IMFP, and Integral Composite Simpson.
