EFFECTS OF TEMPERATURE ON THE NANOTRIBOLOGY OF ZnS AND CdS

In this work, two models were developed through a combination of bond-orbital model, Tomlinson’s model and Sana’s equation. Using the first model,ΔE which is the energy burrier that prevents tip jump was calculated for zinc sulphide (ZnS) and cadmium sulphide (CdS). The second model was used to study the effects of temperature on the nanotribology of the two semiconductors. The results obtained using the first model compares favourably with the values of ΔE obtained using Tomlinson’s model. The results obtained using the second model compares favorably with experimental results for silicon (Si) found in literature. Hence the model was used for ZnS and CdS. There are no experimental results for ZnS and CdS. Hence we are predicting experimental results for these compounds for the first time using our models.
