Abstract

Objectives: To simulate the Monte-carlo simulation of irradiation of alkali ions (sodium) having very low energy (5 keV and 10 keV) on aluminum oxide micro flakes. Methods/Statistical analysis: We have utilized a simulation process namely SRIM (Stopping of ion ranges in matter), which is based on the binary collision approximation technique. We have fixed our target as an aluminum oxide in the layered structure having a thickness about 65 nm. We have incorporated two different types of ion energy as the input parameters which are normally incident on the targets. We have analyzed ion distributions, recoil distributions, and further ionizations. Findings: The projected average range for 10 keV is significantly found to be higher, almost double than that of 5 keV. The reason behind this increment is due to the high penetration depth because of higher energy. The straggling of 10 keV is higher than that of 5 keV, which is evident from the recoil distribution where the cascade collision has created a large volume of vacancies, which is very high for higher energy. Application/Improvements: This simulation helps us to gather a rich amount of information regarding ion-induced defects, which is highly essential for experiments on aluminum oxide micro flakes. The surface modification after this low ion energy bombardment leads to low detrimental effects which may modify the wetting properties of these flakes Keywords: Montecarlo simulation; SRIM; Aluminium oxide micro flakes; ion induced defects; BCA

Summary

Introduction

Aluminum oxide, owing to its various significant chemical, optical and mechanical properties is considered as an effective material[1,2,3]for various industrial applications. Aluminum oxide in nanoscale is often a water remover[4] and CO2 [5] from gas streams It is an efficient hydrocarbon remover from air and water purifier[6] from excessive fluorine content. We have provided a Monte-Carlo based simulation named SRIM[8,9] that can predict the behaviour of aluminium oxide after collision with an alkali ion. After the discovery of various nanomaterials, the importance of irradiation[14] induced effects on these nanostructures was hyped a lot. It has a lot of industrial applications due to its intriguing properties. After getting rich data from the SRIM simulation, the experimentation will be completed in the near future
