EFFECTS OF TEMPERATURE ON THE NANOTRIBOLOGY OF ZINC SELENIDE (ZnSe) AND CADMIUM SELENIDE (CdSe)

摘要

Research work in nanotribology is fast growing with promising results. We developed two models for nanotribology research. The first model was developed through a combination of bond- orbital model and Tomlinson’s model. Using this model, ΔE which is the energy barrier that presents the tip’s jump was calculated for, Zinc Selenide and Cadmium Selenide. The results obtained are in good agreement with those obtained using Tomlinson’s model. The second model was developed through a combination of Tomlinson’s model and Sang’s equation. Because experimental results for Silicon are available, this model was used to study the effects of temperature on the nanotribology of silicon. The results obtained are in good agreement with experimental data for Si found in literature. Hence this model was used to study the effects of temperature on nanotribology of ZnSe and CdSe. There are no experimental results for ZnSe and CdSe. Hence we are predicting experimental results for these compounds for the first time using our models.
